鉴于边坡问题是制约工程建设的主要地质灾害问题之一,基于云模型理论,综合考虑坡高、坡度等多个影响因子,选出10项影响边坡稳定性的指标,由此计算分析各指标隶属于不同岩质边坡稳定性等级的云模型数字特征,并结合正向正态云模型和指标权重,计算待评估边坡的综合确定度,最终确定岩质边坡稳定性等级。以某水电站库岸边坡为例进行建模计算,结果表明该算法可以对边坡的稳定状态进行预测,正确率较高,为比较合理快速地分析边坡稳定性提供了一条新途径。 In view of the slope problem is one of the major geological disasters that constrain the construction of the project, based on the cloud model theory, comprehensive consideration of the slope height, slope and other factors, select 10 indicators that affect the stability of the slope, The numerical characteristics of the cloud model belong to different grades of rock slope stability. Combined with the forward normal cloud model and index weight, the comprehensive determination degree of the slope to be evaluated is calculated and finally the stability grade of the rock slope is determined. Taking a bank slope of a hydropower station as an example, the results show that the algorithm can predict the steady state of the slope with high accuracy, which provides a new way to analyze the slope stability reasonably and quickly.
