滑坡灾害防治工程效果评价方法初探

Study on Evaluation Approach to the Effect of Landslide Hazards Prevention and Control Engineering

摘要:

滑坡防治工程效果评价是一项综合判断与分析的系统工程。通过开展大量滑坡灾害防治工程现场调研，建立了包括滑坡基本要素、治理设计、施工组织、稳定状况、治理效益5项一级评价指标和11项二级指标的评价体系。基于综合模糊层次评价法确定各指标权重并计算防治效果最大隶属度。以三峡库区刘家包滑坡为例，计算表明防治工程效果为优秀，与实际情况相符，验证了此方法的可靠性。

Abstract:

The evaluation of the effect of landslide hazards prevention and control is a systematic project. Based on a great deal of field survey, an evaluation index system including 5 first-level indexes (basic element of landslide, control design, construction organization, stability and treatment benefit) and 11 second-level indexes are established. Based on the comprehensive fuzzy hierarchy estimation, the weight of each index is determined and the maximum subordinate degree of control effect is calculated. Taking the case of Liujiabao landslide in the Three Gorges Reservoir as an example, the calculation shows that the effect of control engineering is excellent; this is consistent with the actual situation, and the reliability of this method is verified.
