| Abstract: | Wave-induced water-head variation may cause steady seepage of pore water in the seabed, producing or leading to instability of the submarine slope. The paper presents a general procedure for the analysis of the relationships among sedimental effective internal friction angle, cohesion, submarine slope angle and critical pore water pressure gradient that causes soils to fail by using a simple limit equilibrium analysis method and the Coulomb failure criterion. The numerical results of critical pore water pressure gradient that causes different soils of the subaqueous Huanghe delta areas to fail are presented in convenient graphical form. Some illustrative field studies are also presented. |
