基于未确知测度理论-反熵法的土质边坡稳定性评价

Safety Evaluation of Soil Slope Stability Based on Unascertained Measure Theory-AEM

为了对影响土质边坡稳定的不确定性因素进行定量分析和定性评价,采用未确知测度理论,实现对影响边坡安全稳定的不同因素的统一度量,并基于影响边坡安全的因素层级构建边坡安全评价指标体系,采用反熵法对评价指标的权重进行客观赋值,实现对多层级、多指标的土质边坡安全稳定性评价。结果表明,该评价方法可以较好地反映边坡安全状态,评价结果与安全鉴定结果一致。

To quantitatively analyze and qualitatively evaluate the uncertain factors that affect the stability of soil slopes,the theory of unascertained measures is adopted to achieve the unified measurement of different factors that affect slope safety and stability,and a slope safety evaluation index system is constructed based on the hierarchy of factors that affect slope safety.The anti-entropy method is used to objectively assign the weights of evaluation indicators for achieving the multi-level and multi index soil slope safety and stability evaluation.The results indicate that the evaluation method can effectively reflect the safety status of slopes,and the evaluation results are consistent with the results of safety appraisal.
