摘要
针对碾压混凝土坝安全性态综合评价中评价指标、指标权重及评价等级的确定所存在的不确定性,将证据理论应用到碾压混凝土坝安全性态综合评价中,以解决评价过程中的不确定性问题。提出了证据理论在碾压混凝土坝安全评价中的计算步骤,建立了碾压混凝土坝安全评价指标体系。通过实例计算,验证了该方法是有效可行的,为碾压混凝土坝安全性态综合评价提供了新的思路。
In view of the uncertainty of evaluation index,weight and grade in comprehensive safety evaluation of roller compacted concrete dam,the evidence theory is applied to the comprehensive safety evaluation of roller compacted concrete dam,which solves the uncertainty problem in the process of the evaluation.The calculation steps of evidence theory are put forward,and the evaluation index system of the dam safety is established.The calculation results show that the presented method is effective,which provides a new concept for the comprehensive evaluation of the dam safety behavior.
