摘　　要：水库坝基加固采用帷幕灌浆是工程中常用的手段。本文结合工程施工应用,对坝基帷幕灌浆的施工技术进行了研究。通过施工前注浆试验和注浆后的压水试验,确定灌浆施工中合理的注浆压力和浆液浓度,对施工过程中出现的特殊情况提出了不同的处理方法,为今后的帷幕灌浆提供了一定的参考。Curtain grouting is a commonly used method in reinforcement engineering for reservoir dam foundation.In this paper,the construction technology of dam foundation curtain grouting is studied in combination with engineering construction application.Through pre construction grouting tests and post grouting water pressure tests,the reasonable grouting pressure and slurry concentration during grouting construction are determined,and different treatment methods are proposed for special situations occurring during construction,which provide a certain reference for curtain grouting in the future.
