摘　　要：总结分析已建水电站厂房的渗漏原因,通过混凝土材料性能分析和材料试验,提出适合高尾水作用下防裂、抗渗混凝土设计指标和混凝土材料,研究细化了止水设计和混凝土的浇筑分层分块,有效解决了厂房混凝土结构的防裂、抗渗技术问题,研究成果已在董箐和沙沱水电站厂房成功应用。Based on the summary and analysis of powerhouse leakage causes of completed hydropower stations,concrete material performance analysis and test, concrete material and its design indicators against crack andleakage under high tail-water level effect are presented in this paper, which provides an effective method to prevent crack and leakage of powerhouse concrete structure. The study results have been successfully applied in thepowerhouses of Dongqing and Shatuo Hydropower Stations.
