【摘要】:基于功效系数法的基本原理,在综合考虑滑坡的关键影响因素基础上,选取滑坡规模、滑坡稳定系数、当日降雨量、潜在经济损失、受灾人数作为评价因子,建立了一种新的滑坡灾害风险评估方法,并将该方法应用于瀑布沟水电站库区12处滑坡灾害评估,评价结果表明,除麦地滑坡实际结果为Ⅲ级而预测结果为Ⅳ级外,结果准确率达到91.7%。这表明基于功效系数法的滑坡灾害风险评估方法是可行的,为滑坡灾害的风险评估提供了一种新的方法。
[Abstract]:Based on the basic principle of efficacy coefficient method, the scale of landslide, landslide stability coefficient, rainfall, potential economic loss and the number of people affected by landslide are selected as evaluation factors on the basis of comprehensive consideration of the key influencing factors of landslide. A new method of landslide hazard risk assessment is established and applied to 12 landslide hazard assessment in Pubugou Hydropower Station reservoir area. The evaluation results show that the actual landslide results are grade 鈪,
