This paper studied the risk assessment of Hujiashan landslide by using geo-slope software and experiential methods, forecasted the affected area, analyzed the unstable probability of the landslide’s multiple hidden sliding surfaces, and made geo-hazards detailed field survey, reconnaissance and analysis of physical and mechanical parameters for samples collected from Hujiashan landslide. Meanwhile, the authors analyzed the landslide hazards and vulnerability of elements at risk under three different conditions: natural state, once-in-ten-years and once-in-fifty-years rainfall state, respectively. On such a basis, the authors completed the Hujiashan landslide risk assessment and discussed the single landslide risk evaluating methods and its work flow. The results indicate that the maximum property risk is 1137100 RMB per year, the maximum people risk is 0.064 8 person per year, which is beyond the tolerable risk criterion of the society.
