Tables for the Hydraulic Design of Pipes, Sewers and Channels: 8th edition, Volume 1 (HR Wallingford titles)

In 1996 a new approach for calculating the axial capacity of driven piles in sand and clay was published by the Marine Technology Directorate (MTD). The design methods are based on four large research projects into offshore pile behaviour at Imperial College London, and co-funded by Industry and MTD. Axial capacity is often the governing criterion when designing driven piles and the approach has been applied world-wide since 1996 in offshore, marine and onshore projects. The new approach is based on effective stress measurements and provides greater reliability and accuracy when compared to existing design methods. This second edition, published by Thomas Telford Ltd, broadens and updates the original work. Contributions are added by Lehane, Overy and standing, that emphasise the wide range of potential civil engineering applications, report relevant research completed since 1996 and refer to lessons learned through several years of practical application.Substantial new sections are included on the selection of appropriate factors of safety, the selection of geotechnical parameters, case histories, non-cylindrical pile shapes, ageing processes, a wider range of soil types (including calcareous sands), group action and cyclic/seismic loading.
