积石峡水电站混凝土面板堆石坝坝体分区优化设计及坝料调整

Dam materials modification and design optimization of zoning of CFRD for Jishixia hydropower project

按照"充分利用开挖料上坝,达到坝料平衡"的指导思想,积石峡水电站混凝土面板堆石坝在大坝填筑之前,先后两次对坝体分区进行了设计优化。在遵循混凝土面板堆石坝设计原则的前提下,合理调整大坝设计断面,合理规划料源,确定坝料具体技术要求,积累了相关的工程经验。

In accordance with the guide of ＂fully utilizing the excavated materials to realize the balance of materials and dam construction＂,the design of dam zoning was optimized twice before placement of the Jishixia CFRD.On the premise of obeying the design principle of CFRD,the dam design section was reasonably modified,the material resources were reasonably planned,and the technical requirements of dam materials were determined,so that relative engineering experience was accumulated.
