Furthermore, it is found that under different cyclic loads, both the surrounding pore pressure and the displacement of the plate...

... are subjected to cyclic loads from wind and waves. Cyclic loads can lead to an accumulation of deformations in the saturated soil as well as to an accumulation of excess pore water pressures with corresponding reductions in strength or bearing capacity. The latter is of particular importance under...
