This book was released on 2013 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geotechnical engineers encounter some of the most challenging problems in heavily overconsolidated soils. Clays under this condition originated in nature or man-made construction. This thesis investigates the mechanical behavior heavily overconsolidated Resedimented Boston Blue Clay (RBBC), as an analog test material. The uniformity, reproducibility, and extensive knowledgebase on this clay permit the investigation of only the effect of overconsolidation. A series of undrained triaxial compression shear tests have been performed on specimens that were Ko-consolidated and swelled to overconsolidation ratios (OCR) ranging from 5 to 62 on RBBC, as well as on Intact Presumpscot Maine Clay. Specimens were consolidated to maximum stress levels between 1.1 and 5.4 MPa. The undrained shear behavior revealed an important relationship with overconsolidation ratio. The triaxial compression test results exhibit a significant increase in the undrained strength ratio (su/[sigma]'vc) when normalized to the minimum consolidation stress. It also shows an important increase in the stiffness, increase in the strain ([epsilon]f) to mobilize the peak resistance and a significant increase of friction angle ([phi]') with overconsolidation. The applicability of the SHANSEP equation and impact on its equation parameters are also discussed in detail. A comprehensive comparison of the new results with prior normally consolidated and lightly overconsolidated data is presented, showing the distinct behavior of heavily overconsolidated specimens. The failure envelope displays a non-linear behavior and the undrained shear strength (su) is reduced up to about 80% from a normally consolidated clay to a heavily overconsolidated clay with an OCR = 50. These observations demonstrate the importance of selecting appropriate design values in the presence of overconsolidated soils.

Download or read book Soil Strength and Slope Stability written by J. Michael Duncan and published by John Wiley & Sons. This book was released on 2014-09-22 with total page 336 pages. 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 Geotechnical Slope Analysis written by Robin Chowdhury and published by CRC Press. This book was released on 2023-11-30 with total page 823 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition of Geotechnical Slope Analysis is an updated version of the original scholarly book. In this edition, concepts and applications have been thoroughly revised. In particular, the ‘Initial Stress Approach’ has been extended to 2D problems in a more rigorous manner. Additional solved numerical examples have been added in several chapters. More importantly, the meaning of the results is explored through interpretation. The influence of initial stresses, pore water pressures and seismic forces has been explored not only on performance indicators such as the ‘Factor of Safety’ but also on the location of critical slip surfaces. In addition to these factors, it is shown that the chosen method of analysis may also have a significant influence on the location of the critical slip surface. Student exercises have been included in some chapters with a view to encouraging further study and research, and reference is often made to case studies of particular importance. The best features of the book have been retained with continued emphasis on both deterministic and probabilistic approaches for quantifying slope performance. The traditional performance indicator such as ‘Factor of Safety’ can be complemented by the calculation of the ‘Reliability Index’ and the ‘Probability of Failure’. This book focuses on research studies concerning slope behaviour, the occurrence of landslides and the use of alternative methods of analysis and interpretation. The importance of uncertainties in slope performance and, more broadly, in geotechnical engineering is emphasised. This book will be valuable to undergraduate and senior students of civil, mining and geological engineering as well as to academic teachers and instructors and also to researchers, practising geotechnical engineers and consultants.

Download or read book Correlations of Soil and Rock Properties in Geotechnical Engineering written by Jay Ameratunga and published by Springer. This book was released on 2015-12-11 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a one-stop reference to the empirical correlations used extensively in geotechnical engineering. Empirical correlations play a key role in geotechnical engineering designs and analysis. Laboratory and in situ testing of soils can add significant cost to a civil engineering project. By using appropriate empirical correlations, it is possible to derive many design parameters, thus limiting our reliance on these soil tests. The authors have decades of experience in geotechnical engineering, as professional engineers or researchers. The objective of this book is to present a critical evaluation of a wide range of empirical correlations reported in the literature, along with typical values of soil parameters, in the light of their experience and knowledge. This book will be a one-stop-shop for the practising professionals, geotechnical researchers and academics looking for specific correlations for estimating certain geotechnical parameters. The empirical correlations in the forms of equations and charts and typical values are collated from extensive literature review, and from the authors' database.

Book excerpt: With continued economic development and increasing urbanization, excavations go deeper and become larger in scale, and are sometimes even carried out in difficult soils. These conditions require advanced analysis and design methods and construction technologies. Most books on general foundation engineering introduce the basic analysis and design of excavation, but do not delve into practical considerations. This book examines both theory and practice, from basic to advanced, and discusses the major methods currently in practice around the world. Each chapter also includes problems and their solutions to develop a practical, real-world understanding.

Download or read book Measuring in Situ Mechanical Properties of Pavement Subgrade Soils written by David E. Newcomb and published by Transportation Research Board. This book was released on 1999 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis report will be of interest to pavement and geotechnical design and research engineers, geologists and engineering geologists, and related laboratory personnel. It describes the current practice for measuring in situ mechanical properties of pavement subgrade soils. The tests conducted to measure the mechanical properties of soil strength and stiffness are the primary topics, and these are discussed in the context of design procedures, factors affecting mechanical properties, and the variability of measurements. Information for the synthesis was collected by surveying U.S., Canadian, and selected European transportation agencies and by conducting a literature search. This TRB report provides information on existing and emerging technologies for static and dynamic, and destructive and nondestructive testing for measuring in situ mechanical properties of pavement subgrade soils. Correlations between in situ and laboratory tests are presented. The effects of existing layers on the measurement of subgrade properties, and soil spatial and seasonal variability are discussed. Most importantly, the use of soil properties in pavement design and evaluation are explained. New applications or improvements to existing test methods to support the use of mechanistic/stochastic-based pavement design procedures are also explained.
