摘　　要：洪屏抽水蓄能电站上水库西副坝坝址地质条件差,地形凌乱。招标和技施阶段,根据对坝址区地形地质条件的进一步分析,对左右岸大坝体形、材料分区、趾板基础开挖与结构等开展设计优化工作。通过设计优化,采取了降低左岸趾板上游边坡高度,并加强边坡处理;取消右岸高趾墙;加强趾板帷幕灌浆等处理措施,在相同的投资条件下,简化了施工工艺,提高了大坝运行的安全性。The dam site of west sub dam of upper reservoir in Hongping Pumped-storage Power Station has a poor geological condition and messy terrain. During tendering and construction drawing design periods, the designs of left and right bank dam body shape, material partition, and foundation excavation and structure of toe slab are optimized according to further analysis on geological conditions of dam area. By design optimization, the height of left bank slope is reduced and the slope treatment is strengthened, the right high toe wall is canceled, and the curtain grouting of toe slab area is strengthened. Through above optimizations, the construction process is simplified and the safety of dam operation is improved under same investment condition.
