Download or read book Engineering Policy Guidelines for Design of Earth Slopes written by and published by . This book was released on 2011 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: These guidelines were developed as part of a comprehensive research program undertaken by the Missouri Department of Transportation (MoDOT) to reduce costs associated with design and construction of bridge foundations while maintaining appropriate levels of safety for the traveling public. The research program was conducted by faculty, students, and staff from the University of Missouri and Missouri University of Science and Technology in collaboration with MoDOT personnel and private industry. The research program was completed in Fall 2010. These guidelines, along with several others, serve as the principal deliverables from the research program. The guidelines were established from a combination of existing MoDOT Engineering Policy Guide (EPG) documents, from the 4th Edition of the AASHTO LRFD Bridge Design Specifications with 2009 Interim Revisions, and from results of the research program. Some provisions of the guidelines represent substantial changes to current practice to reflect advancements made possible from results of the research program. Other provisions were left essentially unchanged, or were revised to reflect incremental changes in practice, because research was not performed to address those provisions. Some provisions reflect rational starting points based on judgment and past experience from which further improvements can be based. All of the provisions should be considered as "living documents" subject to further revision and refinement as additional knowledge and experience is gained with the respective provisions. A number of specific opportunities for improvement are provided in the commentary that accompanies the guidelines.

Available in PDF, EPUB and Kindle. Book excerpt: This book is aimed at the practising engineer and engineering geologist working in tropical environments, where lands lides are mainly triggered by rain fall. This book is based on a similar work published in 1999 in Portuguese, which became the Rio de Janeiro Slope Manual. This book is an engineering guide for the design of slopes and stabilisation works in rocks and residual soils. It evolves from the cumulative experience gathered by several engineers and geologists who faced severe slope problems. The authors' experience throughout Central and South America (Costa Rica, Argentina, Bolivia, Peru, Ecuador and Venezuela) and the Far East, especially Hong Kong and Malaysia, was used as a foundation for writing this book. The work also benefits enormously from the time spent in Hong Kong in 1996 and 1997 by the first editor on sabbatical at the City University of Hong Kong, and the discussions he had with many colleagues from the Geotechnical Engineering Office (GEO) of the Hong Kong Government, especially Dr. A. Malone, Mr. w.K. Pun, Dr. A. Li, Mr. K. Ho, and Mr. y.c. Chan among others.

Available in PDF, EPUB and Kindle. Book excerpt: Provides a complete guide to the study, design, construction and management of landslide and slope engineering measures for mountain roads, with emphasis on low-cost. The geographical focus is on the tropics and sub-tropics, but is also highly relevant to other regions where heavy rain, steep slopes and weak soils and rocks combine to create slope instability. The causes and mechanisms of landslides are described, and the hazards they pose to mountain roads are illustrated. Methods of desk study, field mapping and ground investigation are reviewed and illustrated, with emphasis on geomorphological and engineering geological techniques. The design and construction of alignments, earthworks, drainage, retaining structures, the stabilization of soil slopes and rock slopes, and the control of erosion on slopes and in streams covered. Slope management as part of road maintenance and operation is reviewed, and procedures for risk assessment and works prioritization are described.
Download or read book Guidelines for Open Pit Slope Design in Weak Rocks written by Derek Martin and published by CSIRO PUBLISHING. This book was released on 2018-01-10 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weak rocks encountered in open pit mines cover a wide variety of materials, with properties ranging between soil and rock. As such, they can provide a significant challenge for the slope designer. For these materials, the mass strength can be the primary control in the design of the pit slopes, although structures can also play an important role. Because of the typically weak nature of the materials, groundwater and surface water can also have a controlling influence on stability. Guidelines for Open Pit Slope Design in Weak Rocks is a companion to Guidelines for Open Pit Slope Design, which was published in 2009 and dealt primarily with strong rocks. Both books were commissioned under the Large Open Pit (LOP) project, which is sponsored by major mining companies. These books provide summaries of the current state of practice for the design, implementation and assessment of slopes in open pits, with a view to meeting the requirements of safety, as well as the recovery of anticipated ore reserves. This book, which follows the general cycle of the slope design process for open pits, contains 12 chapters. These chapters were compiled and written by industry experts and contain a large number of case histories. The initial chapters address field data collection, the critical aspects of determining the strength of weak rocks, the role of groundwater in weak rock slope stability and slope design considerations, which can differ somewhat from those applied to strong rock. The subsequent chapters address the principal weak rock types that are encountered in open pit mines, including cemented colluvial sediments, weak sedimentary mudstone rocks, soft coals and chalk, weak limestone, saprolite, soft iron ores and other leached rocks, and hydrothermally altered rocks. A final chapter deals with design implementation aspects, including mine planning, monitoring, surface water control and closure of weak rock slopes. As with the other books in this series, Guidelines for Open Pit Slope Design in Weak Rocks provides guidance to practitioners involved in the design and implementation of open pit slopes, particularly geotechnical engineers, mining engineers, geologists and other personnel working at operating mines.
Download or read book Guidelines for Open Pit Slope Design written by John Read and published by CSIRO PUBLISHING. This book was released on 2009-11-09 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Guidelines for Open Pit Slope Design is a comprehensive account of the open pit slope design process. Created as an outcome of the Large Open Pit (LOP) project, an international research and technology transfer project on rock slope stability in open pit mines, this book provides an up-to-date compendium of knowledge of the slope design processes that should be followed and the tools that are available to aid slope design practitioners. This book links innovative mining geomechanics research into the strength of closely jointed rock masses with the most recent advances in numerical modelling, creating more effective ways for predicting rock slope stability and reliability in open pit mines. It sets out the key elements of slope design, the required levels of effort and the acceptance criteria that are needed to satisfy best practice with respect to pit slope investigation, design, implementation and performance monitoring. Guidelines for Open Pit Slope Design comprises 14 chapters that directly follow the life of mine sequence from project commencement through to closure. It includes: information on gathering all of the field data that is required to create a 3D model of the geotechnical conditions at a mine site; how data is collated and used to design the walls of the open pit; how the design is implemented; up-to-date procedures for wall control and performance assessment, including limits blasting, scaling, slope support and slope monitoring; and how formal risk management procedures can be applied to each stage of the process. This book will assist in meeting stakeholder requirements for pit slopes that are stable, in regards to safety, ore recovery and financial return, for the required life of the mine.

Available in PDF, EPUB and Kindle. Book excerpt: Although most mining companies utilise systems for slope monitoring, experience indicates that mining operations continue to be surprised by the occurrence of adverse geotechnical events. A comprehensive and robust performance monitoring system is an essential component of slope management in an open pit mining operation. The development of such a system requires considerable expertise to ensure the monitoring system is effective and reliable. Written by instrumentation experts and geotechnical practitioners, Guidelines for Slope Performance Monitoring is an initiative of the Large Open Pit (LOP) Project and the fifth book in the Guidelines for Open Pit Slope Design series. Its 10 chapters present the process of establishing and operating a slope monitoring system; the fundamentals of pit slope monitoring instrumentation and methods; monitoring system operation; data acquisition, management and analysis; and utilising and communicating monitoring results. The implications of increased automation of mining operations are also discussed, including the future requirements of performance monitoring. Guidelines for Slope Performance Monitoring summarises leading mine industry practice in monitoring system design, implementation, system management, data management and reporting, and provides guidance for engineers, geologists, technicians and others responsible for geotechnical risk management.

Download or read book Graphical Determinations of Earth Slope Retaining Walls and Dams written by Charles Prelini and published by CreateSpace. This book was released on 2015-06-08 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author states that this book ls intended for students and not for professional engineers, but the subject treated is one of deep interest to civil engineers as well. The stability of earth slopes is considered, in the first chapter, on the basis of the angle of natural slope due to the internal friction of the material, and also by including with the friction the cohesion of the soil which is found to exist in old well settled banks. The subject is treated both graphically and analytically. The slope of equal stability as affected by height of bank when cohesion is considered is then constructed, bringing out the steep top and flat bottom, which is characteristic of the natural earth slope. Comparisons are then made of the amounts of excavation per lin. ft. for a 50-ft. cut taken out to different uniform slopes, with those obtained for corresponding slopes of equal stability or equal safety and the saving in excavation shown. The pressure of earth against retaining walls is taken up graphically in Chapter II., using the method given by Rebhann. The treatment includes the irregular profile or surcharge, also the effect of cohesion for walls supporting firm undisturbed earth free from water and frost. The passive pressure or the resistance of earth to motion from the horizontal thrust of say an arch is also considered. The analytical method from Rebhann is developed in Chapter III., while the formulas of Rankine and Weyrauch are given without derivation. No account is taken of cohesion in this chapter. At the close of the chapter three tables are given showing the close numerical agreement between the three methods for heights of wall from 25 to 85 ft. for different batters and for different surcharges. The design of retaining walls is considered in Chapter IV. The method is extended to walls with buttresses and counterforts, the latter both with and without relieving arches, but it is not extended to reinforced-concrete construction. Masonry dams are briefly discussed in the last chapter. The stability of earth slopes and the earth pressure against retaining walls are well presented in the first three chapters. Attention is called to earth slopes as they actually occur and to the assumptions made by Rebhann in developing the methods used in finding the pressures against retaining walls. The chapter on the design of retaining walls would have been of greater value to the student or to the young practicing engineer if it had been put more in touch with actual practice by considering the effects of character of soil, drainage, frost, and even of foundations upon stability, as was done for earth slopes, and by a. few illustrations from practice. These applications would have been especially valuable in showing the application of theory to practice, an application which is questioned by many engineers. An extension of the chapter to reinforced-concrete retaining walls in connection with the European system of buttresses, counterforts and relieving arches would have greatly enhanced the value of the book, even if added at the expense of the chapter on dams. The treatment of masonry dams is brief, but a pretty good general idea is given of the methods of computing stability and of determining practical cross-sections with illustrations from European and American practice. The typography is excellent. -Engineering News, Volume 60 [1908]

Available in PDF, EPUB and Kindle. Book excerpt: The definitive guide to the critical issue of slope stability and safety Soil Strength and Slope Stability, Second Edition presents the latest thinking and techniques in the assessment of natural and man-made slopes, and the factors that cause them to survive or crumble. Using clear, concise language and practical examples, the book explains the practical aspects of geotechnical engineering as applied to slopes and embankments. The new second edition includes a thorough discussion on the use of analysis software, providing the background to understand what the software is doing, along with several methods of manual analysis that allow readers to verify software results. The book also includes a new case study about Hurricane Katrina failures at 17th Street and London Avenue Canal, plus additional case studies that frame the principles and techniques described. Slope stability is a critical element of geotechnical engineering, involved in virtually every civil engineering project, especially highway development. Soil Strength and Slope Stability fills the gap in industry literature by providing practical information on the subject without including extraneous theory that may distract from the application. This balanced approach provides clear guidance for professionals in the field, while remaining comprehensive enough for use as a graduate-level text. Topics include: Mechanics of soil and limit equilibrium procedures Analyzing slope stability, rapid drawdown, and partial consolidation Safety, reliability, and stability analyses Reinforced slopes, stabilization, and repair The book also describes examples and causes of slope failure and stability conditions for analysis, and includes an appendix of slope stability charts. Given how vital slope stability is to public safety, a comprehensive resource for analysis and practical action is a valuable tool. Soil Strength and Slope Stability is the definitive guide to the subject, proving useful both in the classroom and in the field.

Download or read book Stability Analysis of Earth Slopes written by Y.H. Huang and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past several years I have been engaged in applied research related to the stability analysis of slopes. This research was supported by the Institute for Mining and Minerals Research, University of Kentucky, in response to the Surface Mining Control and Reclamation Act of 1977, which requires stability analysis for refuse dams, hollow fills, and spoil banks created by surface mining. The results of the research have been published in several journals and reports and also presented in a number of short courses. Both the sim plified and the computerized methods of stability analysis, as developed from this research, have been widely used by practicing engineers throughout Ken tucky for the application of mining permits. The large number of out-of-state participants in the short courses indicates that the methods developed have widespread applications. This book is a practical treatise on the stability analysis of earth slopes. Special emphasis is placed on the utility and application of stablity formulas, charts, and computer programs developed recently by the author for the analy sis of human-created slopes. These analyses can be used for the design of new slopes and the assessment of remedial measures on existing slopes. To make the book more complete as a treatise on slope stability analysis, other methods of stability analysis, in addition to those developed by the author, are briefly discussed. It is hoped that this book will be a useful reference, class room text, and users' manual for people interested in learning about stability analysis.
