The 9th edition maintains the content on all soil mechanics subject areas - groundwater flow, soil physical properties, stresses, shear strength, consolidation and settlement, slope stability, retaining walls, shallow and deep foundations, highways, site investigation - but has been expanded to include a detailed explanation of how to use Eurocode 7 for geotechnical design.   The key change in this new edition is the expansion of the content covering Geotechnical Design to Eurocode 7. Redundant material relating to the now defunct British Standards -  no longer referred to in degree teaching - has been removed.   Building on the success of the earlier editions, this 9th edition of Smiths Elements of Soil Mechanics brings additional material on Geotechnical Design to Eurocode 7 in an understandable format.  Many worked examples are included to illustrate the processes for performing design to this European standard.   Significant updates throughout the book have been made to reflect other developments in procedures and practices in the construction and site investigation industries. More worked examples and many new figures have been provided throughout. The illustrations have been improved and the new design and layout of the pages give a lift.   unique content to illustrate the use of Eurocode 7 with essential guidance on how to use the now fully published code clear content and well-organised structure takes complicated theories and processes and presents them in easy-to-understand formats         The website  The book's companion website www.wiley.com/go/smith/soil provides you with resources and downloads to further your understanding of the fundamentals of soil mechanics and the use of Eurocode 7: A suite of editable spreadsheets which map onto the worked examples in the book, showing how they are solved  Solutions to the end-of-chapter exercises, including the full workings Convenient tables with useful data and formulae
