Liquefaction and Strength of Saturated Sand During Cyclic Loading

In this paper the indexes of pore water pressure and dynamic strength of saturated sand are carried out under various stress conditions by applying double-action cyclic triaxial test system. These results can be used as a reference in the stabilily analysis of saturated sand foundations and slopes against earth-quake. Moreover, the V-phenomena in the wave peak of the time history of pore water pressure by the characteristic of volume swelling of dense sand under shearing stress are investigated.
