基于地震力的滑坡稳定性分析

概述了滑坡稳定性与地震力的关系．以剩余推力法为基础推导了基于地震力的滑坡稳定性计算公式及步骤。根据该公式计算的几个滑坡稳定性结果，得出了在滑坡稳定性评价中是否考虑地震力很有可能得出截然不同的结果，进而影响正确作出是否对滑坡进行治理的决策的结论。由此可见，地震力的作用是滑坡稳定性分析中一个不可忽视的因素。

Stability Analysis of Slope Based on the Seismic Force

By summarizing the relationship between stability of landslide and seismic force,this paper describes the seismic force in landslide and establishes the formula of stability and its calculating process on the basis of the unbalanced driving force method. Through the calculation of some cases, it finds that taking account for the seismic force has an important effect on the analysis of stability. Therefore, the seismic force is one of the factors that cannot be neglected in the stability analysis of the slope.
