摘要
为了能准确评价边坡的稳定性,降低边坡治理过程中发生滑坡事故的风险,借鉴可拓学原理,将熵权法和层次分析法复合应用于指标综合权重的确定,建立以地形地貌等4个1级指标和以坡高、坡角等16个2级指标组成的边坡稳定性多级可拓评价模型,对边坡稳定性进行评价。研究表明,将物元可拓理论应用于边坡稳定性评价是可行的,应用该模型得到的边坡总体稳定性与实际边坡情况相吻合,可以很好地预测边坡的安全状态。
In order to evaluate the stability of slope accurately and reduce the risk of landslide accident during the treatment of slope, the analysis of entropy method and AHP method are combined to determine the comprehensive weight of evaluation index based on the principles of extenics, and then the multi-level extension evaluation model of slope stability is established to evaluate the stability of slope. The model takes four first-grade indexes such as topographic and geomorphology and sixteen twograde indexes such as slope height and slope angle as index system. The research shows that the application of matter element extension theory to the evaluation of slope stability is feasible, and the slope stability obtained by this model agrees well with actual slope condition. The model can well predict the safety state of slope.
