基于TOPSIS与灰色关联法的水库大坝安全指数评价OA

The indexes that affect the safety and reliability of reservoir generally have the characteristics of outstanding hierarchy and uncertainty.According to the characteristics of each index and related standards,6 dimensions and 19 evaluation indexes are selected,and the index system which can reflect the safety state of reservoir is constructed by combining reservoir safety assessment with TOPSIS and grey correlation method.The results show that the safety degree of the five reservoirs from high to low is:Liuliuzhuang Reservoir,Guanlou Reservoir,Shuangchakou Reservoir,Shazigang Reservoir and Ershimudi Reservoir.The result is basically consistent with the expert evaluation,which shows the accuracy and applicability of this method;the model can effectively reduce the subjective influence of scoring,and the evaluation result is more scientific,so it has a good application prospect and guiding significance for practical engineering.
