摘要
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 hydrogeological condition of a dam foundation, the experimental data of pressing water to drilling and grouting to dam foundation, the water permeability of dam foundation, the feasibility and necessity of curtain grouting to the dam foundation are discussed. It is concluded that under the advantageous hydrogeological condition for dam foundation to prevent seepage, a more wide range of grouting index can be adopted in grouting.
