通过动力三轴试验，给出了饱和砂的残余孔隙水压力的全量表达式和不同液化破坏阶段的临界孔隙水压力比的表达式。
Expressions of total residual pore pressure and critical ratio of pore pressure in different failure stages of liquefaction in saturated sand are deduced based on the dynamic tri-axial tests.
黏弹性流体饱和多孔介质模型比采用单相介质或者弹性饱和孔隙介质更接近实际的土层介质，来该模型来研究土层介质的动力响应更为合理。
The fluid saturated porous viscoelastic media is closer to actual stratum than Biot media and single-phase media, and the researches on its dynamic response will be more reliable.
