摘要
为了更好地加固治理病险水库,针对加固方案决策,提出一种多目标决策方法,该方法引入AHP-EM组合赋权法。首先收集病险水库大坝加固方案的决策指标,采用AHPEM组合赋权法进行组合权重赋予,以此来评价决策方案可行性。结果显示,在多方案评价中,从研究所选取的多个指标中选出最优方案,并对最优方案进行仿真和应用测试:仿真显示研究选取方案能够显著降低大坝孔隙压力,应用显示能够将大坝的垂直位移降低至0.026m。研究表明,多目标决策能够选出病险水库大坝加固的最优施工方案,在病险水库大坝加固和长期治理中具有重要作用。
In order to better strengthen dangerous reservoirs,a multi-objective decision-making method for reinforcement scheme decision-making is proposed,in which AHP-EM combined weighting method is introduced.Firstly,the decision-making indexes of the dam reinforcement scheme of the dangerous reservoir are collected,and the AHP-EM combination weighting method is used to give the combination weighting to evaluate the feasibility of the decision-making scheme.The results show that in the evaluation of multiple schemes,the optimal scheme is selected from the multiple indicators selected by the research,and the optimal scheme is simulated and tested.The simulation shows that the scheme selected by the research can significantly reduce the pore pressure of the dam,and the application shows that the vertical displacement in the dam can be reduced to 0.026m.The above results show that the multi-objective decision-making can select the optimal construction scheme for dam reinforcement of dangerous reservoirs,and it is important in dam reinforcement and long-term treatment of dangerous reservoirs.
