摘　　要：石泉大坝右岸非溢流坝段扬压力超标问题自第一次安全定期检查提出后,曾做过大量的加固研究工作,但效果一直不明显。本文对扬压力超标成因进行了分析,同时介绍了新近实施的帷幕化学灌浆的施工过程及施工工艺,并对最后的灌浆质量做出了评价。The problem of uplift pressure being higher in non-overflow sections at the right bank of Shiquan dam has come up since the first dam safety inspection,a lot of studies and work have been done but got lower effect.This article analysed the reasons why the uplift pressure exceeded it being.Moreover,the construction procedure and technique on curtain chemical grouting newly con-ducted in Shiquan dam are introduced and assessment is made as well.
