基于可拓理论的边坡稳定性评价
|
摘要
为了确保边坡的稳定性,减少边坡治理过程中发生事故的可能性,运用可拓学的原理,将熵权法、层次分析法结合起来,综合确定复合权重,建立包含4个一级指标和16个二级指标的边坡稳定性多级可拓评价模型,用以评价边坡的稳定程度。经过研究发现,应用物元可拓性的方法进行边坡稳定性评价是可行的,得到的结果与边坡实际的状况是一致的,可以提前预测出边坡的安全隐患,做好预防工作。
In order to ensure the stability of the slope in reducing the possibility of accidents during the slope treatment, this paper uses the principle of extenics to combine the entropy weight method and the analytic hierarchy process to comprehensively determine the composite weights. It has established four multi-level extension evaluation models for slope stability of the first-level indicators and sixteen secondary indicators to evaluate the stability of the slope. After this research, we know that it is feasible to use the matter-element extension method to evaluate the slope stability. The obtained results are consistent with the actual situation of the slope. It is possible to predict the safety hazard of the slope in advance and do a good job of prevention.
