Abstract

This dissertation studies the behaviour of the standard cone penetrometer in stratified clay sediments, using large deformation FE method. The underlying soil flow mechanisms and the form of the penetration resistance profiles are exposed. CPT data interpretation frameworks (including identification of layer boundaries and extracting accurate strength values for each identified layer) were established for three layer clay deposits with an interbedded either stiff or soft layer, and then extended to more general multilayer clay deposits that cover a practical range of interests in design.
