Available in PDF, EPUB and Kindle. Book excerpt: This dissertation is a compilation of four papers submitted to scholarly geotechnical engineering journals. Each paper includes references to literature reviewed, research data, and significant findings. The first paper presents an experimental study performed to investigate the influence of induced lateral stress on shear strength, vertical stiffness, and preconsolidation pressure of the reconstituted Iowa loess. Four series of stress path control tests were conducted in which soil specimens remolded from western Iowa loess, were consolidated under increased lateral stress before being loaded vertically in either drained or undrained fashion. The second paper describes a numerical analysis using an axisymmetric, finite element model to study the behavior of isolated rammed aggregate piers subjected to compressive load. The load transfer mechanism along pier shaft and pier-soil interactions is particularly investigated in this paper. Constitutive parameters of the materials involved in the numerical analysis were determined from in-situ and laboratory tests. The finite element model was validated by comparing the numerical results with the data obtained from full-scale, instrumented load tests. The third paper presents results from full-scale, instrumented load tests conducted on two trial square pier-supported footings and three isolated rammed aggregate piers. Group effects are investigated by comparing the behavior of an individual pier within the pier group and an isolated pier from the same diameter and length. Evaluation of the current design methods for computing bearing capacity of pier-supported footing is carried out by comparing the calculated parameters with the measured values. The fourth paper presents a numerical study on the support mechanism of rammed aggregate pier groups. The numerical study focuses on the group behavior of rammed aggregate piers and the vertical stress distribution underneath the footings. A modulus-based method developed based on the homogenization approach combined with the finite element stress distribution for estimating footing settlement is also presented in this paper.

This book was released on 2012-02-11 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stone columns have been used since the 1950's as a technique for soil improvement such as cohesive soils and silty cohesion less soils. Stone column's applications includes (1) stabilizing the foundation soils to support embankments, approach fills and reconstruction work on weak cohesive soils, (2) supporting retaining structures (including Reinforced Earth), bridge bent and abutment structures on slightly marginal soft to stiff clays and loose silty sands, (3) landslide stabilization and (4) reducing liquefaction potential of clean sands. Also, stone columns under proper conditions may be greatly decrease the time required for primary consolidation. The stone column technique of ground behavior has proven successful in (1) improving slope stability of both embankments and natural slopes, (2) increasing bearing capacity, (3) reducing total and differential settlements, (4) reducing the liquefaction potential of sands and (5) increasing the time rate of settlement. Stone column construction involves the partial replacement of unsuitable subsurface soils with a compacted vertical column of stone that usually completely penetrates the weak strata. When jetting water is used the process is named vibro-replacement and when used without jetting water in partially saturated soils such as old rubble fill, the process is known as vibro-displacement. This book can be help to engineers and researchers on stone columns. I would also like to thank my parents and my wife. The author is grateful to the engineers for their efforts in preparing the excellent works included in the world. The author has helped provide to the profession significant information on which to base current decisions on soil improvement and on which to build for future works.
Download or read book Principles and Practice of Ground Improvement written by Jie Han and published by John Wiley & Sons. This book was released on 2015-05-26 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gain a stronger foundation with optimal ground improvement Before you break ground on a new structure, you need to analyze the structure of the ground. Expert analysis and optimization of the geo-materials on your site can mean the difference between a lasting structure and a school in a sinkhole. Sometimes problematic geology is expected because of the location, but other times it's only unearthed once construction has begun. You need to be able to quickly adapt your project plan to include an improvement to unfavorable ground before the project can safely continue. Principles and Practice of Ground Improvement is the only comprehensive, up-to-date compendium of solutions to this critical aspect of civil engineering. Dr. Jie Han, registered Professional Engineer and preeminent voice in geotechnical engineering, is the ultimate guide to the methods and best practices of ground improvement. Han walks you through various ground improvement solutions and provides theoretical and practical advice for determining which technique fits each situation. Follow examples to find solutions to complex problems Complete homework problems to tackle issues that present themselves in the field Study design procedures for each technique to simplify field implementation Brush up on modern ground improvement technologies to keep abreast of all available options Principles and Practice of Ground Improvement can be used as a textbook, and includes Powerpoint slides for instructors. It's also a handy field reference for contractors and installers who actually implement plans. There are many ground improvement solutions out there, but there is no single right answer to every situation. Principles and Practice of Ground Improvement will give you the information you need to analyze the problem, then design and implement the best possible solution.

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.
