| 摘 要： | Introduction A sudden rupture of fault in the crust induces intensive earthquake, and brings about the overlaying soil moving and cracking, and the Earth′s surface deforming and rupturing as well. When it crosses the foundations of buildings and the underground structures, the rupture close to the Earth′s surface or surface fault would lead to direct destruction to these structures. The study on this problem has been paid more attention in recent years. From Kobe Earthquake, Izimit Earthq…

| Abstract: | In this paper, the rupture characteristics of the overlaying soil with soft interlayer were studied by plane-strain finite element method. From the results, it can be shown that the existence of soft layer separates rupture process of the overlaying soil into two phases. The depth of a buried soft interlayer will influence the rupture process and the rupture range of the overlaying soil. The deeply buried soft interlayer would bring about a wider range of surface failure. In addition, the thickness of the soft layer also has effect on the rupture process and rupture range of the overlaying soil. |
