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。
In view of the lack of systematic analysis of the selection of cement sand gravel dam, the engineering adaptability of the construction of the cement sand gravel dam is analyzed. The main factors affecting the selection of the type of the cement sand gravel dam are summarized. Based on the classical theory and method of multi-attribute decision-making, corresponding dam-type evaluation index, combined with AHP and entropy weight method, the model of selection and selection of cement sand and gravel dam is established. Combining with the example of NH reservoir dam project, this project is realized by Matlab software, and the selection and selection process of this project is realized. The results are in line with the recommended dam type of feasibility study report, and the validity of this model is validated. Provide a reference for similar projects.
