摘　　要：为解决边坡稳定性风险评价问题,采用G1法和熵权法,提出一种主客观权重相结合的方法,分别对边坡稳定性风险评价指标进行主观和客观权重赋值,采用拉格朗日乘子法确定组合权重,用于边坡风险等级预测,最终得出边坡的风险评价结果。西双版纳傣族自治州的波罕、丹兰和章芭地块的边坡风险评价结果表明,该方法评价结果与实际结果基本吻合,证明该方法的有效性和可行性,为边坡风险评价提供一种方法和思路。In order to solve the problem of slope stability risk assessment,a method of combining subjective and objective weights is proposed by using G1 method and entropy weight method to assign the subjective and objective weights of slope stability risk assessment indexes,respectively,then the combined weights are determined by Lagrange multiplier method,which is used to predict the risk level of slope,and finally the risk assessment results of slope are obtained.The slope risk assessment results of Bohan,Danlan and Zhangba plots in Xishuangbanna Dai Autonomous Prefecture show that the evaluation results of this method are basically consistent with the actual results,which proves the effectiveness and feasibility of this method,and provides a method and idea for slope risk assessment.
