Abstract: Based on the meachnical behaviors of representative soil layer in Shanghai, several computation profiles with different soil layer constructions are built. An effective-stress procedure, in which the bounding surface hypoplasticity model and Biot consolidation formulation are coupled, is used to analyze the effect of soil layer constructions on liquefaction of sandy soil. The results show: the thickness of covering soil layer increases, peak pore pressure ratio of sandy soil decreases; when it is softer, shear stress of sandy soil increases firstly, then decreases; but harder, it increases continuously. The deeper underlying soil layer is, the smaller peak pore pressure ratio and the more shear stress of sandy soil is; both are not obvious. But, if softer, the peak pore pressure ratio of sandy soil changes more sharply.

Key words: soil layer construction, sand liquefaction, effective stress, hypoplasticity
