摘要
Abstract
Based on the basic principle of the efficacy coefficient method,a new method for assessing land slide disaster risk is established herein by selecting landslide scale,landslide stability coefficient,intraday rainfall,potential economic losses,number of disaster victims as the assessment factors under the comprehensive consideration of key impacting factors of landslide,and then the method is applied to the hazard assessment made on 12 landslides occurred within the reservoir area of Pubugou Hydropower Station;from which the assessment result shows that its accuracy reaches 91.7%,except that the actual result of the risk level for Maidi Landslide is Ⅲ,but its predicted result is Ⅳ.It is indicated that the efficacy coefficient method-based landslide disaster risk assessment method is feasible and provides a new method for landslide disaster risk assessment as well.关键词
