Comprehensive evaluation method and application of barrier dam development and utilization
摘要
Abstract
At present,most of the engineering design and construction of barrier dams'development and utilization follow the tra-ditional technical theory of earth-rock dams,and after the completion of emergency rescue,risk analysis,and feasibility analysis of development and utilization,there is no quantitative evaluation method for the development and utilization effect of barrier dams.By analyzing the development and utilization needs of barrier dams such as social benefit and ecology,water supply and irrigation,power generation function,and return on investment,a comprehensive evaluation index system and a multi-level fuzzy comprehensive eval-uation model for the development and utilization of barrier dams were established.The weight of each index was determined by intro-ducing the analytic hierarchy method improved by the cloud model,and the membership degree of each index was determined by combining the constructed membership degree function.The development and utilization effect of typical barrier dams in China was comprehensively evaluated by taking the dams of Hongshiyan,Tangjiashan,Baige,and Zhouqu debris flow as typical cases.The re-sults showed that the comprehensive evaluation system of barrier dam development and utilization met the evaluation requirements of maximizing demand effectiveness and benefits,and the improved multi-level fuzzy comprehensive evaluation model better solved the problems of randomness and discreteness of evaluation indicators.The comprehensive evaluation results were consistent with the ac-tual situation of the project,and the evaluation system and model had good applicability.The research results can provide theoretical reference and a practical basis for the comprehensive evaluation of barrier dam development and utilization.关键词
