Abstract: Because of lowflood prevention ability, higher damfoundation uplift pressure than standard and the uncertainty of the fault F2 , damsafety and stability was effected. As a result, Xianghongdian reservoir damwas classified as Grade 3. This paper introduced the investigation test of damfoundation uplift pressure, analysed the cause reason and advanced the treatment advice.

摘要： 响洪甸水库大坝被评定为三类坝, 其最主要原因是该库的防洪能力不足、大坝坝基扬压力过高和F2 断层难以确定, 严重影响大坝的安全稳定。本文主要对坝基扬压力过高的探查试验情况进行介绍, 对产生的原因进行分析, 并提出了处理方案的设想。
