Applicability of solutions for transient wave‐induced porewater pressures in seabed and liquefaction conditions of seabed.
抄録(英):
There exist three solutions for the transient wave‐induced porewater pressures in seabed, the seepage flow solution16), the exact solution6) and the boundary region approximation solution10) of Biot's consolidation equations9). Applicability of three solutions is shown graphically in terms of non‐dimensional parameter for surf zone conditions. One of the important parameters is the ratio of the shear modulus of solid skelton to the effective bulk modulus of porewater. Another is a non‐dimensional quantity proportional to the permeability coefficient and the shear modulus. As the former becomes large and the latter becomes small, the seepage flow solution can not be used but the boundary region approximation solution becomes applicable. Under such situation, the possibility of the vertical effective stress of solid skelton being zero under the wave trough increases. The maximum depth of zero stress is about one half of the wave height.
