An accessible, clear, concise, and contemporary course in geotechnical engineering, this key text strikes a balance between theory and practical applications for an introductory course in soil mechanics. Mechanics are kept to a minimum so that students can appreciate the background, assumptions, and limitations of the theories. The book discusses the implications of key ideas to provide students with an understanding of the context for their application. A modern explanation of soil behavior is presented, particularly in soil settlement and soil strength. Substantial online resources are offered to support teaching and learning.
