注浆在水库病险处理中的应用

Application of Grouting in Reinforcement of Reservoir Dam

大坝渗漏是水库病险中的主要现象,对水库的安全运行构成了严重威胁。分析了水库大坝渗漏的主要原因,决定采用注浆对大坝进行除险加固,注浆后压水试验表明,渗透系数最大为1.89×10-5cm/s,最小为1.86×10-7cm/s。实践证明注浆是一种有效处理大坝渗漏的方法。

The leakage of reservoir dam is the major phenomena of reservoir trouble; it is great danger for work of reservoir. The reasons of the leakage of reservoir was analyzed. The leakage of reservoir dam was treated by grouting and the effect of treatment of grouting was checked. The results of check show that the maximum of penetration coefficient is 1. 89 × 10^-5 cm/s and the minimum of penetration coefficient is 1. 86 × 10^-7 cm/s. It was proved that the grouting is an effective treatment method of leakage of reservoir dam.
