基于区间数群决策的土石坝施工期度汛方案风险评价
Risk Evaluation of Flood Control Scheme During the Construction Period of Earth-Rock Dam Based on Interval Number Group Decision
摘要
Abstract
The flood resistance ability of rock dam during the construction is insufficient,and the choice of flood control scheme directly af-fects the safety risk and cost risk of the project.However,there is relatively little research on the collaborative control of safety risk and cost risk of flood control scheme during the construction of earth-rock dam.At the same time,the evaluation index in multi-objective cooperative control involves many professional fields,and a single expert has different grasp of each evaluation index,so it is difficult to assign an accu-rate value.Therefore,a number of experts are used to assign values to evaluation indicators in the form of interval numbers,and an expert group opinion negotiation model is built by minimizing the distance of indicator values assigned among experts,and the value of interval num-bers assigned by many experts is converted into a point that integrates all expert opinions,so as to establish a safety risk and cost risk evalua-tion model of flood control scheme during the construction period of earth-rock dam.Taking Qianping Reservoir as an example,a comprehen-sive evaluation of 7 flood schemes was carried out to guide the construction of Qianping Reservoir,and the collaborative control of safety risk and cost risk was realized.关键词
