摘要
九牛岭大坝因填筑质量差,坝体渗水严重,几次工程处理后,效果仍不理想,一直带病运行.1983年11月至1984年3月对大坝进行了劈裂灌浆处理,为了进一步探讨灌浆后的效果,布置了观测孔.实测资料及其分析研究表明:劈裂灌浆显著改善了坝体渗流状态,坝体情况不会恶化,保证了大坝的安全.
There existed unfavorable condition in Jiuniuling Earth Dam during its operating period due to serious percolation caused by poor fill. The situation was not improved although several construction measures had been taken. Crack grouting had been carried out from Nov. 1983 to March 1984. Some observation holes were arranged to examine the effect of grouting. Observation and nalysis indicate that the perealation state has been obviously improved and the dam safety can he ensured.
