摘要： 为将水平和竖向地震作用对边坡稳定性的影响加以量化，以一典型边坡为例，采用有限元强度折减法分别分析了水平地震作用、竖向地震作用、以及水平和竖向地震共同作用对边坡稳定性的影响，并且结合我国相关抗震规范，对不同抗震等级地区考虑地震作用的必要性进行了量化分析计算，结果表明在7度及以上地区考虑水平地震作用是有必要的，对9度区必须考虑竖向地震作用。

Abstract: In order to quantify the influence of horizontal and vertical seismic actions on the slope stability, a typical slope is taken as an example. The finite element strength reduction method was used to analyze the influence of horizontal seismic actions only, vertical seismic actions only, and combined horizontal and vertical seismic actions on the slope stability. The seismic actions in different seismic magnitude areas were also considered in combination with the relevant seismic codes of China. The results show that it is necessary to consider the horizontal seismic action in the area of earthquake magnitude 7 degree and above, and it is necessary to consider the vertical seismic action in the area of magnitude 9 degree.

Key words: Horizontal Seismic Action, Vertical Seismic Action, Finite Element Strength Reduction Method, Seismic Magnitude, PseudoStatic Method
