Landslide is a phenomenon that the rock and soil mass on the slope slides down along a certain sliding surface under the action of gravity,which is mainly caused by terrain,lithology,geological structure and hydrological conditions.In China,the vast majority of provinces have landslide disaster,with Yunnan,Sichuan and other places are the most serious,Inner Mongolia and parts of the northwest because of flat terrain,or desert areas,less landslide disasters.In this paper,taking the highway landslide prevention project in a mountainous area as an example,through the analysis of the survey data,we have a certain understanding of the material composition,structural characteristics and movement characteristics of the landslide.On this basis,the cause analysis and stability evaluation of the landslide are conducted,and the management plan is put forward according to the deformation law,so as to achieve the purpose of disaster prevention and mitigation.
