Experimental and Numerical Studies on Wave-Induced Instability in Suction Caisson Foundation Founded in the Seabed
This extended abstract presents both experimental and numerical studies on the instability of suction caisson foundation founded in a dense non-cohesive seabed. A series of model scale wave flume tests were conducted to investigate the instabilities of both rectangular and circular suction caisson foundations subjected to various wave conditions. The pore water pressure responses around the caisson tip and across the caisson top cap were measured during the tests. A two-dimensional finite element tool, namely SWANDYNE II, was employed to verify the observed pore pressure responses around the rectangular caisson in the tests. The linear elastic finite element solutions successfully verified the hypotheses observed from the wave flume tests.
