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.
