摘要

地震和暴雨同时作用是自然界中引发边(滑)坡灾害的一种极端工况。在分析地震和暴雨同时作用于边(滑)坡的稳定性时，现行规范只能采用将地震及暴雨影响简单叠加的方法。采用GEO-SLOPE软件，对川藏公路和西攀高速公路上的典型边(滑)坡工点，采用动力有限元与极限平衡理论相结合的方法，分析它们在地震和暴雨共同作用下的稳定性，探索采用将地震与暴雨工况简单叠加，以及地震和暴雨耦合分析这两种方法评价边(滑)坡稳定性的差别，并对现行规范计算方法的适用性作出评价。结果表明，地震和暴雨的耦合作用对边(滑)坡稳定性的影响大于地震、暴雨单独作用的叠加对边(滑)坡稳定性影响。

Abstract

The joint effect of earthquake and rainstorm is the extreme condition which causes landslide in nature.The current co des to evaluate the impacts of both earthquake and rainstorm on slope stability are just a simple addition of the two factors.By using the GEOSLOPE software and employing dynamics element infinite and limit equilibrium theory

this paper evaluates the stability of the typical slope sites along the Sichuan—Tibet highway and Xichang—Panzhihua freeway under the coupling of earthquake and rainstorm

in order to find the difference of simple addition and the coupling analysis of earthquake and rainstorm

and also evaluates the applicability of regular computational methods.Research has found that the coupling of earthquake and rainstorm has more serious impacts to slope stability than the simple addition of impact of earthquake and rainstorm alone.
