Abstract: Tianshui Village landslide is located in Tianshui village, Zhangjiabian town, Suide County. On the basis of geological disaster risk investigation in Suide County, the geological conditions and basic characteristics of the landslide are analyzed in detail. At the same time, using the limit equilibrium theory, the stability of the whole slope is calculated in two conditions. The results show that the landslide is basically stable in the natural state and unstable in the rainfall saturation state. In order to prevent the occurrence of geological disasters, combined with the characteristics of the landslide itself, it is suggested to implement slope cutting and weight reduction engineering, drainage engineering and retaining engineering.
