Numerical analysis of liquefaction potential of partially drained seafloors
AbstractThe cyclic normal and shear stresses induced in the seafloor sands by sea waves, generate transient and residual pore-water pressures. When the pore pressure becomes equal to the total normal stress the soil liquefies and loses its strength. This paper presents a numerical method for evaluating pore-water pressure build-up and liquefaction potential of offshore sites, in which partial drainage is implemented through a two-dimensional consolidation model. The effect of soil permeability, relative density and deformability on pore-pressure generation is studied and an application of the method to evaluate the liquefaction potential of a North Sea site is examined.
