Book Progressive Failure in Slopes Stability

Download or read book Progressive Failure in Slopes Stability written by Agnese Murianni and published by LAP Lambert Academic Publishing. This book was released on 2011 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the stability analysis of earth slopes the simple computational methods, referred to the classical limit equilibrium approach, are not able to predict complex processes as progressive failure. Such a phenomenon can be studied only using procedures that are able to simulate the formation and development of a shear band in which plastic strains localise. From a computational point of view, this presents many problems, because the numerical analyses, carried out with local elasto-plastic models, are affected by a lack of convergence and the solution depends strongly on the mesh adopted. For this purpose, a non-local elasto-viscoplastic model, implemented in the finite element code TOCHNOG, is proposed in this book. In order to assess the validation of the model, two ideal examples are analysed: a plane strain compression test and a stability analysis of a slope with a given groundwater level. The proposed approach allows to overcome the problems of the local elasto-plastic models and, therefore, it can represent a useful analysis tool of progressive failure for the geotechnical engineers.

Book Slope Analysis

Download or read book Slope Analysis written by R Chowdury and published by Elsevier. This book was released on 2012-12-02 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Slope Analysis summarizes the fundamental principles of slope analysis. It explores not only the similarities but also the differences in rock slopes and soil slopes, and it presents alternative methods of analysis, new concepts, and new approaches to analysis. The book introduces both natural and man-made slopes, the nature of soils and rocks, geomorphology, geology, and the aims of slope analysis. These topics are followed by chapters about stress and strain, shear strength of rock and soils, and progressive failure of slopes. This book also presents limit equilibrium methods I and II, which are the planar failure surfaces and slip surfaces of arbitrary shape, respectively. It also includes stress analysis and slope stability, natural slope analysis, and a brief review on plasticity and shear band analysis. Before presenting its conclusions, the book discusses special aspects of slope analysis, such as earthquake analysis, pseudo-static analysis, dynamic analysis, and anisotropy, in addition to Newmark’s approach.

Book Meshless Analysis Method for the Whole Process of Progressive Failure of Slope

Download or read book Meshless Analysis Method for the Whole Process of Progressive Failure of Slope written by Zhang Xiaoqiang and published by . This book was released on 2024-02-12 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The slope failure is a large deformation problem, the traditional numerical method finite element method (FEM), and limit equilibrium method (LEM) is difficult to characterize the whole process of the failure, resulting in the mechanism analysis which is not clear. In this work, a mesh-free particle approach, named the smoothed particle hydrodynamics (SPH) method, is presented and is improved to analyze the damage and failure process of a rock slope. In order to better describe the cause and mechanism of brittle failure for rock slope, the plastic factor was suggested and introduced into the SPH algorithm, and the conservation equations of SPH for brittleness characteristics were obtained. For soil slope, its instability mechanism and failure mode are different from that of rock slope. Therefore, this work also introduces the application of the smoothed particle hydrodynamics (SPH) method in the instability evolution process of soil slope. Firstly, an improved method for solving the SPH safety factor based on the adaptive discount factor method is proposed, the tolerance value is introduced, the relationship between the displacement increment and the tolerance value of the characteristic point is analyzed, and the real displacement mutation point is determined. Secondly, the SPH numerical model of slope is established to analyze the characteristics of slope deformation and failure, which shows that the SPH method can effectively represent the whole process of slope instability and progressive failure and effectively overcome the disadvantage of non-convergence when the traditional numerical method is used to study the deformation and failure of geotechnical materials.

Book Deformation and Progressive Failure in Geomechanics

Download or read book Deformation and Progressive Failure in Geomechanics written by A. Asaoka and published by Elsevier. This book was released on 1997-10-23 with total page 956 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progressive failure has been a classical problem in the field of geotechnical engineering and has attracted considerable attention in connection with slope stability and foundation problems. It is associated with strain localization or shear banding and is also related to damage in material structures. As knowledge of the progressive failure mechanism increases, it is now necessary to establish effective communications between researchers and engineers. The International Symposium on Deformation and Progressive Failure in Geomechanics provided an opportunity for discussing recent advances in this area. A total of 136 papers were contributed from 22 countries. As well as these, the symposium proceedings also contain 8 interim technical reports on the subject by the members of the Asian Technical Committee of the International Society for Soil Mechanics and Foundation Engineering and the Japanese Geotechnical Society National Committee on Progressive Failure in Geo-structures.

Book Stability Analysis of Earth Slopes

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.

Book Soil Mechanics

Download or read book Soil Mechanics written by David Muir Wood and published by Cambridge University Press. This book was released on 2009-09-28 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book teaches the principles of soil mechanics to undergraduates, along with other properties of engineering materials, to which the students are exposed simultaneously. Using the critical state method of soil mechanics to study the mechanical behavior of soils requires the student to consider density alongside effective stresses, permitting the unification of deformation and strength characteristics. This unification aids the understanding of soil mechanics. This book explores a one-dimensional theme for the presentation of many of the key concepts of soil mechanics - density, stress, stiffness, strength, and fluid flow - and includes a chapter on the analysis of one-dimensional consolidation, which fits nicely with the theme of the book. It also presents some theoretical analyses of soil-structure interaction, which can be analyzed using essentially one-dimensional governing equations. Examples are given at the end of most chapters, and suggestions for laboratory exercises or demonstrations are given.
