摘要 研究目的:为科学、快速判识黄土边坡突发滑坡地质灾害的风险,预防地质灾害的发生,研究黄土边坡产生滑坡的影响因素及其风险等级和权重,以及各影响因素下黄坡边坡突发滑坡地质灾害的风险等级,为地质病害体的防治提供参考、为病害的消除赢得时间、为病害点的规避提供科学依据,同时可以预防或减轻地质灾害发生后造成的人员伤亡和财产损失。
研究结论:(1)构建了基于综合指数法的黄土边坡突发滑坡地质灾害风险判识和评估方法,明确了评估原则,提出11种判识评价指标因子,并给出了各指标的权重以及对各评估指标和综合指数计算结果进行了风险等级划分;(2)通过实例应用和演算,该方法评估结果与实际基本吻合;(3)通过该方法评为“高风险”和“极高风险”的边坡(滑坡),应提出预警并及时规避或采取相应的治理措施;(4)本文评估方法可应用于黄土边坡地质灾害评价及防治中,具有借鉴意义。

Abstract：Research purposes: In order to scientifically and quickly identify the risk of sudden landslide geological disasters on loess slope and prevent the occurrence of geological disasters, this paper studies the influencing factors, risk grade and weight which influence loess slope landslide, and the risk grade of sudden landslide geological disaster of loess slope under various influencing factors conditions, to provide reference for the prevention and control of geological diseases, win time for the elimination of diseases, also provide a basis for avoiding disease points, and prevent or reduce the casualties and property losses caused by geological disasters.
Research conclusions:(1) This paper constructs the risk identification and evaluation method of sudden landslide on loess slope based on comprehensive index method, clarifies the evaluation principles, puts forward 11 kinds of identification and evaluation index factors, give the weight of each index factor, and classifies the risk grade of each evaluation factor and the calculation results of the comprehensive index. (2) Through the example application and calculation, the evaluation results of this method are basically consistent with the actual situation. (3) For slopes (landslides) rated as "high risk" and "extremely high risk" by this method, early warning should be given and corresponding treatment measures should be taken to avoid or take measures in time. (4) This evaluation method can be applied to the evaluation and prevention of geological disasters in loess slope, and has reference significance.

Key words： loess slope landslide identification and evaluation composite index
