... ABSTRACT In the present paper, the liquefaction potential and the change in effective stress associated with the gap between the water pressure on the ground surface and the pore water pressure in the ground induced by tsunami inundation have been numerically studied. From the numerical...

.... The pressure gradually decreases from the neighborhood of well to surrounding layers and MH dissociation occurs. It is predicted that the sediment deformation and consolidation occurs due to MH dissociation and increases the effective stress during depressurizing operation. Consolidation and deformation...

... and overtops a coastal dyke, there is a possibility that liquefaction occurs by earthquakes and promotes scour at the landward toe. Liquefaction is caused by a decrease in effective stress. Therefore, it is important to evaluate the influence of the effective stress on the scour due to overtopping...

... and instability of a rubble-mound breakwater. Particularly, the instantaneous liquefaction of seabed around the rubble foundation of a typical breakwater cross-section is evaluated based on the mean effective stress criterion. Analysis of breakwater-seabed system as a whole requires accurate modeling of soil...

...) method to track the free surface of water. The seabed is treated as porous medium and characterized by Biot s partly dynamic (u-p) formulations. Using this model, we study the distribution of pore pressure and effective stress of seabed under cnoidal wave, solitary wave and random wave. Numerical results...
