Abstract

Predictions of changing strength of fine-grained soils due to strain-rate, remoulding, and consolidation processes are crucial to design and stability analysis of 'whole-life' behaviour of several geotechnical structures, such as seabed cables, pipelines, and anchoring systems. This thesis incorporates the changing strength of soft soils into numerical analyses via a combination of constitutive and applied modelling techniques. The numerical analyses involved development and implementation of two strain-softening-hardening constitutive models which were incorporated in simulations of T-bar and ring penetrometer tests in order to investigate changing strength and frictional properties of soft sediments. The results were compared with experiments.
