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.
在循环加、卸载孔隙水压力作用下，残余应变与循环次数的关系符合乘幂负指数关系。
The relationship between the residual strain and cyclic Numbers accords with the power of negative index under the cyclic loading and unloading pore water pressures.
