通过分析某工程坝址水文地质条件、钻孔压水试验资料及坝基灌浆试验资料,对坝基帷幕灌浆可灌性及必要性进行了探讨。认为在坝基具体水文地质条件有利于防渗的情况下,灌浆指标可适当放宽。
By analyzing the hydrogeological conditions of dam site, drilling pressure test data and grouting test data of dam foundation, the feasibility and necessity of curtain grouting in dam foundation are discussed. It is considered that the grouting index may be properly relaxed under the condition that dam hydrogeology conditions are conducive to seepage control.
