【摘要】 针对胶凝砂砾石坝坝型比选尚缺乏系统分析的现状,分析了胶凝砂砾石坝大坝建设的工程适应性,总结了影响胶凝砂砾石坝坝型比选的主要因素,提出了相应的坝型评价指标,采用多属性决策经典理论和方法,运用改进层次分析法、熵权法进行组合赋权,建立胶凝砂砾石坝型比选模型。结合NH水库大坝工程实例,以Matlab软件为工具,编程实现了该工程坝型比选决策过程,比选结果与可行性研究报告推荐坝型一致,验证了该比选模型的有效性,可为类似工程提供参考。更多还原

【Abstract】 According to the current lack of system analysis of cement-sand-gravel dam type selection,engineering adaptability in construction of the dam was analyzed.The main factors for influencing the selection of cement-sand-gravel dam were summarized and the corresponding evaluation index of dam type was put forward.Based on the multi-attribute decision making,improved analytic hierarchy process and entropy weight were adopted to determine combination weight and the dam type selection model was built.Taking the NH reservoir engineering as an example,using Matlab as tool,the decision process of dam type selection was completed.The reliability and practicality of the dam type selection model are verified by examining the consistency of the dam type selection results and the dam type recommended in feasibility study stage of the project.Thus,it provides reference for the similar project.更多还原
