Abstract: After curtain grouting and the drainage at the dam foundation, comparing with the situation before, the paper analysed the seepage and uplift pressure of Santunhe reservoir damsystematically, and the results showed that the seepage and uplift pressure had decreased a lot. It can be learned that the measure is effective. And the conclusion can be gotten that the water level is a main factor which effects the seepage and uplift pressure.

摘要： 根据三屯河水库大坝采取帷幕灌浆和坝基排水前后情况, 应用对比分析方法, 对坝基扬压力和渗流进行了系统分析表明, 采取该措施后, 坝基扬压力和渗流大幅度削减, 说明该措施效果显著。同时, 库水位是影响坝基扬压力和渗流的主要因素, 并得出了相应结论和建议, 为今后三屯河水库大坝安全监测运行管理提供科学依据。
