摘　　要：阐述了目前国内外在滑坡地震稳定性评价方面的理论研究成果和实际应用情况,指出地质矿产行业规范在采用静力法计算地震力时没有乘以0.25的综合影响系数,和其它规范的差别是巨大的。分析后认为这个规定是值得商榷的。最后根据宏观震害现象提出易引起滑坡的地质情况并对其进行了分析,为滑坡治理工程设计和以后的规范修编提供了方法和思路。Domestic and foreign currently research and practical application of the landslide stability evaluation theory was described in the paper.Compared the four norms about the earthquake force calculation that the geology and mineral resources industry norms which calculate the seismic forces in the static method is no influence coefficient multiplied by 0.25,which has enormous difference to the other norms,So this provision in the norms is debatable by many examples analysis.Finally,according to the Macro earthquake damage phenomenon the geological situation which cause landslide was put forward and analyzed,the methods and ideas for landslide control engineering design and specification revision were put forward.
