Geotechnical Problems And Solutions

This book covers problems and their solution of a wide range of geotechnical topics. Every chapter starts with a summary of key concepts and theory, followed by worked-out examples, and ends with a short list of key references. It presents a unique collection of step by step solutions from basic to more complex problems in various topics of geotechnical engineering, including fundamental topics such as effective stress, permeability, elastic deformation, shear strength and critical state together with more applied topics such retaining structures and dams, excavation and tunnels, pavement infrastructure, unsaturated soil mechanics, marine works, ground monitoring. This book aims to provide students (undergraduates and postgraduates) and practitioners alike a reference guide on how to solve typical geotechnical problems. Features: Guide for solving typical geotechnical problems complementing geotechnical textbooks. Reference guide for practitioners to assist in determining solutions to complex geotechnical problems via simple methods.

A simplified approach to applying the Finite Element Method to geotechnical problems Predicting soil behavior by constitutive equations that are based on experimental findings and embodied in numerical methods, such as the finite element method, is a significant aspect of soil mechanics. Engineers are able to solve a wide range of geotechnical engineering problems, especially inherently complex ones that resist traditional analysis. Applied Soil Mechanics with ABAQUS® Applications provides civil engineering students and practitioners with a simple, basic introduction to applying the finite element method to soil mechanics problems. Accessible to someone with little background in soil mechanics and finite element analysis, Applied Soil Mechanics with ABAQUS® Applications explains the basic concepts of soil mechanics and then prepares the reader for solving geotechnical engineering problems using both traditional engineering solutions and the more versatile, finite element solutions. Topics covered include: Properties of Soil Elasticity and Plasticity Stresses in Soil Consolidation Shear Strength of Soil Shallow Foundations Lateral Earth Pressure and Retaining Walls Piles and Pile Groups Seepage Taking a unique approach, the author describes the general soil mechanics for each topic, shows traditional applications of these principles with longhand solutions, and then presents finite element solutions for the same applications, comparing both. The book is prepared with ABAQUS® software applications to enable a range of readers to experiment firsthand with the principles described in the book (the software application files are available under "student resources" at www.wiley.com/college/helwany). By presenting both the traditional solutions alongside the FEM solutions, Applied Soil Mechanics with ABAQUS® Applications is an ideal introduction to traditional soil mechanics and a guide to alternative solutions and emergent methods. Dr. Helwany also has an online course based on the book available at www.geomilwaukee.com.

Devised with a focus on problem solving, Geotechnical Problem Solving bridges the gap between geotechnical and soil mechanics material covered in university Civil Engineering courses and the advanced topics required for practicing Civil, Structural and Geotechnical engineers. By giving newly qualified engineers the information needed to apply their extensive theoretical knowledge, and informing more established practitioners of the latest developments, this book enables readers to consider how to confidently approach problems having thought through the various options available. Where various competing solutions are proposed, the author systematically leads through each option, weighing up the benefits and drawbacks of each, to ensure the reader can approach and solve real-world problems in a similar manner The scope of material covered includes a range of geotechnical topics, such as soil classification, soil stresses and strength and soil self-weight settlement. Shallow and deep foundations are analyzed, including special articles on laterally loaded piles, retaining structures including MSE and Tieback walls, slope and trench stability for natural, cut and fill slopes, geotechnical uncertainty, and geotechnical LRFD (Load and Resistance Factor Design).

Soil-structure interaction is an area of major importance in geotechnical engineering and geomechanics Advanced Geotechnical Engineering: Soil-Structure Interaction using Computer and Material Models covers 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.

This book include research studies which deal with the attempts to address new solutions for challenges in geotechnical engineering such as characterization of new materials, application of glass fibre, geotextile fabric and permeable concrete, new numerical methods for traditional problems and some other geotechnical issues that are becoming quite relevant in today's world. The book adds to the geotechnical engineering field which still bears lots of big challenges. It contributes to make the civil infrastructures more sustainable using new technologies and materials that have been proposed and applied in various fields. Papers were selected from the 5th GeoChina International Conference 2018 – Civil Infrastructures Confronting Severe Weathers and Climate Changes: From Failure to Sustainability, held on July 23 to 25, 2018 in HangZhou, China.

The currently available soil mechanics textbooks explain theory and show some practical applications through solving abstract geotechnical problems. Unfortunately, they do not engage students in the learning process as students do not "experience" what they study. This book employs a more engaging project-based approach to learning, which partially simulates what practitioners do in real life. It focuses on practical aspects of soil mechanics and makes the subject "come alive" through introducing real world geotechnical problems that the reader will be required to solve. This book appeals to the new generations of students who would like to have a better idea of what to expect in their employment future. This book covers all significant topics in soil mechanics and slope stability analysis. Each section is followed by several review questions that will reinforce the reader’s knowledge and make the learning process more engaging. A few typical problems are also discussed at the end of chapters to help the reader develop problem-solving skills. Once the reader has sufficient knowledge of soil properties and mechanics, they will be offered to undertake a project-based assignment to scaffold their learning. The assignment consists of real field and laboratory data including boreholes and test results so that the reader can experience what geotechnical engineering practice is like, identify with it personally, and integrate it into their own knowledge base. In addition, some problems include open-ended questions, which will encourage the reader to exercise their judgement and develop practical skills. To foster the learning process, solutions to all questions are provided to ensure timely feedback.
