Applied Analysis in Geotechnics
The problems and procedures facing the practising geotechnical engineer are becoming increasingly complex, relying heavily on numerical models and analysis by specialised software packages. Applied Analyses in Geotechnics provides in-depth coverage of a wide range of geotechnical subjects normally found only in more specialised literature. Innovative
and state-of-the-art, 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, Applied Analyses in Geotechnics will enable the reader to make informed judgements about appropriate analytical parameters and allow for greater understanding of results and their implications.
