The problems and procedures facing the practising geotechnical engineer are becoming increasingly complex, relying heavily on numerical models and analysis by specialized software packages. This book provides in-depth coverage of a wide range of geotechnical subjects normally found only in more specialized literature. Using clear illustrations and numerous worked examples, the book explains core, yet highly complex topics such as critical state modelling, centrifuge modelling, pressuremeter testing and finite element modelling. Aimed at the geotechnical student and practising engineer, it should enable the reader to make informed judgements about appropriate analytical parameters and allow for greater understanding of results and their implications.
