Available in PDF, EPUB and Kindle. Book excerpt: An investigation has been conducted to gain a better understanding of the drained residual and fully softened shear strengths of cohesive soils, the shear strength mobilized in field case histories involving previous and no previous sliding in stiff clays, and develop empirical relationships that describe the stress-dependent nature of the residual and fully softened shear strengths in terms of soil index properties. To investigate the drained residual strength, a Bromhead ring shear apparatus was modified to allow testing of overconsolidated, presheared, remolded soil specimens of different plasticity and clay-size fraction. Residual shear strengths measured using the modified ring shear apparatus were compared to shear strengths measured in conventional reversal direct shear tests on precut remolded specimens and shear strength values back-calculated from well documented field case histories of slopes that underwent previous sliding. The modified ring shear, direct shear, and triaxial compression apparatuses were used to investigate the fully softened shear strength using normally consolidated, remolded specimens. The natural soils used in the residual and fully softened research have a range of liquid limit of 24 to 286%, plasticity index of 8 to 244%, and clay-size fraction of 10 to 88%. New relationships describing the residual and fully softened friction angles developed from the extensive ring shear testing were presented in terms of the liquid limit, clay-size fraction, and effective normal stress. Most of the existing residual and fully softened strengths relationships are based on only one soil index property and provide a friction angle that is independent of effective normal stress. The importance of incorporating the liquid limit, clay-size fraction, and effective normal stress in estimating the residual and fully softened friction angles was illustrated using field case histories. Several first-time slides through stiff fissured clays were also studied to estimate the shear strength mobilized during failure. Based on these studies and laboratory test results, recommendations for estimating the field shear strength of stiff fissured clay involved in first-time slides were presented. A reanalysis of the 1981 upstream slide in San Luis Dam was conducted to evaluate the shear strength reduction caused by the displacement induced by repeated loading. The effect of plasticity and degree of overconsolidation on this shear strength reduction was investigated.

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 Slope Stability Analysis of a Fissured Glacial Clay written by Byron G. Walker and published by . This book was released on 1966 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A slope in an over-consolidated, fissured clay was analyzed by the Swedish Method of Slices. Values of cohesion (c) and angles of friction (Ø) were determined by three different types of direct shear tests (undrained, drained and residual). Factors of safety (functions of c and Ø) indicated that the direct shear test parameter gave a factor of safety approximately four times that represented by failure conditions in the field. Drained tests gave a factor of safety nearly 2.3 times the value represented by field conditions. The conclusion is made that these two tests are of limited value for slope stability analyses in stiff fissured clays. The residual strength tests gave factors of safety values close to those represented by field conditions (1.2 and 1.1 versus 1.0 - 0.8 and 0.6 versus 1.0 for a theory modification). Further studies are required to evaluate the residual shear strength approach as a general method of analysis"--Abstract, leaf ii.

Available in PDF, EPUB and Kindle. Book excerpt: Freshly updated and extended version of Slope Analysis (Chowdhury, Elsevier, 1978). This reference book gives a complete overview of the developments in slope engineering in the last 30 years. Its multi-disciplinary, critical approach and the chapters devoted to seismic effects and probabilistic approaches and reliability analyses, reflect the distinctive style of the original. Subjects discussed are: the understanding of slope performance, mechanisms of instability, requirements for modeling and analysis, and new techniques for observation and modeling. Special attention is paid to the relation with the increasing frequency and consequences of natural and man-made hazards. Strategies and methods for assessing landslide susceptibility, hazard and risk are also explored. Moreover, the relevance of geotechnical analysis of slopes in the context of climate change scenarios is discussed. All theory is supported by numerous examples.

Prof. Devendra Narain Singh, Indian Inst. of Technology, Mumbai, India ''I have yet to see a book that excels the range and depth of Geotechnical Slope Analysis... I have failed to find a topic which is not covered and that makes the book almost a single window outlet for the whole range of readership from students to experts and from theoreticians to practicing engineers...''

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.
