针对水库除险加固工程的效益评价问题,综合考虑经济、社会、环境三个方面构建效益评价指标体系,采用遗传层次分析法(GA-AHP)确定指标权重,并建立物元分析评价模型(MEAE),分析工程治理效果,为水库的管理和维护提供依据。以宜昌市小溪塔黑湾水库除险加固工程为例,用定性和定量结合的方法量化各指标值,确定评价标准,对工程效益进行评价。结果表明,黑湾水库除险加固大部分效益指标达到了预期效益,与实际情况相符,验证了评价模型的有效性。
According to the benefit evaluation of reservoir reinforcement project, the benefit evaluation index system is constructed considering economic, social and environmental aspects, the weight of indicators is determined by Genetic Analytic Hierarchy Process (GA-AHP), and the material element analysis and evaluation model (MEAE ), Analyze the effect of project management and provide the basis for reservoir management and maintenance. Taking the example of risk elimination and reinforcement of Xiaowan Reservoir in Xiaoxi Pagoda of Yichang City, the index values are quantified by qualitative and quantitative methods, and the evaluation criteria are determined, and the project benefits are evaluated. The results show that most of the benefit indicators of reinforcement and reinforcement of the Black Bay Reservoir have achieved the expected benefits, which is in line with the actual situation, which verifies the validity of the evaluation model.
