摘　　要：大变幅水源水位条件下的泵站取水方式对取水可靠性、工程造价和取水建筑物安全均影响较大,合理评价不同取水方式是工程设计应重点考虑的问题之一。对此,构建了一套由3个定量指标和14个定性指标组成的两层评价指标体系,采用层次分析法和熵权法并基于最小二乘法原理对评价指标进行主观和客观组合赋权,基于隶属度和模糊综合评判法进行不同取水方案的综合评价和优劣排序,并结合具体工程进行分析。结果表明,所提出的指标体系全面,赋权方法合理,评价方法更好体现了方案比选的不确定性。工程实例应用检验了该评价方法的可行性。The water intake mode of pumping station under the condition of large variable water level of water source has great impact on the reliability of water intake,project cost and safety of water intake building,so the reasonable evaluation of different water intake mode is one of the key problems in engineering design.In this paper,a two-level evaluation index system consisting of 3 quantitative indicators and 14 qualitative indicators was constructed.The analytic hierarchy process(AHP),entropy weight method and least square method were used to assign the combination of subjective and objective weights.The method of membership degree and fuzzy comprehensive evaluation was used to evaluate and rank different water intake schemes,and an engineering example was analyzed.The results show that the proposed index system is comprehensive,the weighting method is reasonable,and the evaluation method can better reflect the uncertainty of the scheme selection.The practical engineering example verified the feasibility of the evaluation method.
