... before, and assembled during, installation. Assemblage requires a successive segment to be attached to a formerly penetrated one by welding and often takes one day or more for two segments. During this period of time, the build-up of excess pore pressure in the soil below and around the pile dissipates...

... 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...

... the pore pressure in the soft clays, which becomes unstable over time. The most likely trigger for the sliding is one or a series of strong earthquakes caused by glacio-isostatic rebound following glacial retreat. This explains the tendency of sliding to occur after glacial periods. The Storegga area has...
