Advanced Geotechnical Engineering

Features

 

Examines the limitations of conventional solutions used in solving geotechnical problems pertaining to beams, piles, footings, dams, retainign walls, tunnels, anchors, seepage, consolodation, and earthquake analysis Presents the developments in numerical modeling techniques and tools such as finite element and finite difference methods, analytical procedures, and their applications for solving geotechnical problems in an easily understood manner Includes conventional and advanced developments in constitutive modeling for geologic materials, interfaces and joints Explains the influence of interactions between structures and soils/rocks, effects of nonlinearity, and material models on the behavior of structures Details the software used in solving examples throughout the book Offers a wide range of challenging problems that benefits a broad range of readers (upper-level undergraduate and graduate students, researchers, faculty, and practicing engineers)

 

Summary

 

Soil-structure interaction is an area of major importance in geotechnical engineering and geomechanicsAdvanced Geotechnical Engineering: Soil-Structure Interaction using Computer and Material Modelscovers computer and analytical methods for a number of geotechnical problems. It introduces the main factors important to the application of computer methods and constitutive models with emphasis on the behavior of soils, rocks, interfaces, and joints, vital for reliable and accurate solutions.

 

This book presents finite element (FE), finite difference (FD), and analytical methods and their applications by using computers, in conjunction with the use of appropriate constitutive models; they can provide realistic solutions for soil–structure problems. A part of this book is devoted to solving practical problems using hand calculations in addition to the use of computer methods. The book also introduces commercial computer codes as well as computer codes developed by the authors.

 

 

 

Uses simplified constitutive models such as linear and nonlinear elastic for resistance-displacement response in 1-D problems Uses advanced constitutive models such as elasticplastic, continued yield plasticity and DSC for microstructural changes leading to microcracking, failure and liquefaction Delves into the FE and FD methods for problems that are idealized as two-dimensional (2-D) and three-dimensional (3-D) Covers the application for 3-D FE methods and an approximate procedure called multicomponent methods Includes the application to a number of problems such as dams , slopes, piles, retaining (reinforced earth) structures, tunnels, pavements, seepage, consolidation, involving field measurements, shake table, and centrifuge tests Discusses the effect of interface response on the behavior of geotechnical systems and liquefaction (considered as a microstructural instability)

 

This text is useful to practitioners, students, teachers, and researchers who have backgrounds in geotechnical, structural engineering, and basic mechanics courses.
