DESCRIPTION

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 Smith s 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 * book's website offers examples and downloads to further understanding of the use of Eurocode 7 www.wiley.com/go/smith/soil
