INTRODUCTION TO SOIL MECHANICS
Introduction to Soil Mechanics covers the basic principles of soil mechanics, illustrating why the properties of soil are important, the techniques used to understand and characterise soil behaviour and how that knowledge is then applied in construction. The authors have endeavoured to define and discuss the principles and concepts concisely, providing clear, detailed explanations, and a wellillustrated text with diagrams, charts, graphs and tables. With many practical, worked examples and end-of-chapter problems (with fully worked solutions available at www.wiley.com/go/bodo/soilmechanics) and coverage of Eurocode 7, Introduction to Soil Mechanics will be an ideal starting point for the study of soil mechanics and geotechnical engineering.
This book's companion website is at
