... to settle as predicted. Several interesting soil structure interaction aspects are studied in detail, including redistribution of stresses from the skirt to the base due to dissipation of high excess pore pressure generated during installation, cyclic loading during the winter storms and creep along...

... of consolidation is the piezo- cone dissipation test. The coefficient of consolidation is esti- mated at discrete depths of interest by monitoring the decay of excess pore pressure with time, and comparing the time for a given degree of dissipation with theoretical solutions. The pore pressure can be measured...

... of the law of conservation of energy. The model allows the evaluation of the excess pore pressure generated during gas hydrate dissociation. In the second part of the paper, we present and discuss an application of the numerical model developed in the present work through a back-analysis of an observed slide...
