Abstract: Since its completion in 1953, several rehabilitation projects and curtain grouting were carried out. In order to verify the durability of dam curtain, two test holes on two dam blocks which respectively represented dam curtain constructed in 1989~1994 and in 2008 were selected to undergo 240 h steady water pressure test. Drawing the curve of relationship between the flow and time, we analyzed the durability of the dam curtain in this paper, worthy reference.

摘要： 丰满水电站大坝1953年全部建成以来，历经多次补强帷幕和修补工程。为验证坝体帷幕的耐久性，选取两个坝段2个试验孔（分别代表1989 ~1994年期间施工坝体帷幕和2008年施工坝体帷幕）做240 h稳压压水试验，绘制孔内流量与时间的关系曲线，分析研究坝体帷幕的耐久性。这种专门的混凝土坝体内帷幕耐久性试验资料，在水工建筑物的运行和维护过程中，具有特定角度的参考价值。
