摘要
In this paper, rupture propagation in overlying soil under dip-slip fault displacements is investigated with finite element method,and a finite element model is developed for the overlying soil with excitation of the dip-slip fault displacement.The result shows that: 1) the higher the dip angle of fault is,the bigger vertical displacement would be required to cause surface rupture; 2) loading rate of the fault have some effects on the vertical displacement required to cause surface rupture and on rupture angle of soil because of inertial force; and 3) the type of fault has significant effects on the relation between rupture angle of soil and dilatancy angle,as well as between rupture angle of soil and friction angle.
