Craig's Soil Mechanics, Eighth Edition: A Comprehensive Textbook on Soil Mechanics
Craig's Soil Mechanics, Eighth Edition is a bestselling textbook that blends clarity of explanation with depth of coverage to present students with the fundamental principles of soil mechanics. From the foundations of the subject through to its application in practice, the book provides an indispensable companion to undergraduate courses and beyond.
The book is written by Jonathan Knappett, a lecturer in Civil Engineering at the University of Dundee, UK, and R.F. Craig, a former lecturer in Civil Engineering at the same university. The book is based on the previous editions by R.F. Craig, who is widely regarded as one of the leading authorities on soil mechanics.
The eighth edition of the book has been rewritten throughout in line with Eurocode 7, with reference to other international standards. It also features new topics such as limit analysis techniques, in-situ testing, and foundation systems. Additionally, the book comes with an extensive companion website that offers innovative spreadsheet tools, digital datasets, a solutions manual for lecturers, weblinks, extended case studies, and more.
The book is suitable for students of civil engineering, geotechnical engineering, environmental engineering, and related disciplines. It is also a valuable reference for practising engineers, researchers, and consultants who deal with soil mechanics and geotechnical design.The following sections provide a brief overview of each chapter of the book.
Chapter 1: Basic concepts and definitions
This chapter introduces the basic concepts and definitions of soil mechanics, such as soil phases, soil particles, soil structure, soil weight-volume relationships, specific gravity, unit weight, void ratio, porosity, degree of saturation, water content, and air content. It also explains the difference between coarse-grained and fine-grained soils, and the methods of soil identification.
Chapter 2: Soil classification and compaction
This chapter discusses the importance and methods of soil classification, such as the Unified Soil Classification System (USCS), the British Standard Classification System (BSCS), and the International Soil Classification System (ISCS). It also describes the principles and procedures of soil compaction, such as the standard Proctor test, the modified Proctor test, the field compaction methods, and the factors affecting compaction.
Chapter 3: Effective stress and pore water pressure
This chapter explains the concept of effective stress, which is the stress carried by the soil skeleton. It also covers the pore water pressure, which is the pressure exerted by the water in the soil pores. It shows how to calculate the effective stress and pore water pressure in various situations, such as under hydrostatic conditions, under applied loads, in partially saturated soils, and during drainage and consolidation.
Chapter 4: Permeability and seepage
This chapter deals with the permeability and seepage of soils, which are related to the flow of water through soils. It defines the coefficient of permeability and its units, and describes the factors affecting permeability. It also presents the methods of measuring permeability in the laboratory and in the field. It then introduces the concept of seepage and its consequences, such as piping and heave. It also explains how to analyze seepage problems using Darcy's law, flow nets, seepage forces, and seepage control measures.
Chapter 5: Stress distribution and settlement
This chapter covers the stress distribution and settlement of soils due to external loads. It introduces the concept of stress in soils and its components, such as normal stress and shear stress. It also explains how to calculate the vertical stress at any point below a surface load using Boussinesq's equation and Westergaard's equation. It then discusses the elastic settlement of soils due to compression and shear deformation. It also presents the methods of estimating settlement from laboratory tests and field observations. 0efd9a6b88
