John Atkinson's established textbook is ideal for undergraduates of geotechnical engineering for civil engineers. It sets out the basic theories of soil mechanics in a clear and straightforward way which combines both classical and critical state theories, and delivers a good grounding which will last right through into a career as a geotechnical engineer. The subject is broken down into discrete topics which are presented in a series of short, focused chapters with clear and accessible text that develops from the purely theoretical to practical applications. Soil behaviour is described by relatively simple equations with clear parameters while a number of worked examples and simple experimental demonstrations illustrate the principles involved and aid reader understanding.
