Study on the Method of Hazard Assessment for Single Landslide

Landslide has become the most important problem in urban construction since it can cause a large number of casualties and losses each year.Based on the risk assessment method of landslide hazards both at home and abroad,in this paper we conducted a case study and explored the method of hazard assessment for single landslide.Firstly,the analysis program of Monte-Carlo in accordance with the basic principles has been developed to predict the failure probability of singe landslide.At the same time,the authors made use of a professional software to simulate the trajectories of landslide and determine run-out distance and the range of hazardous areas in accordance with the topography data from the study area.Secondly,the results of hazard assessment can be used to provide the scientific basis for urban construction planning in the area of influence,so as to effectively avoid risks.
