大石桥水库库兴建于动乱年代的特殊时期,大坝填筑质量差,又经过多年运行,大坝坝体、坝基渗漏严重,已危及水库安全。文章详细分析了大坝渗漏的原因,并制定了针对性的加固处理措施,即采用塑性混凝土防渗墙结合帷幕灌浆对坝体、坝基进行了防渗处理,有效的解决了大坝渗漏问题,使水库的防洪效益得以正常发挥,具有一定的推广价值。
Dashiqiao Reservoir was built during the special period of turmoil. The quality of dam filling is poor. After years of operation, the seepage of dam and dam foundation is serious, which has endangered reservoir safety. In this paper, the causes of the seepage of the dam are analyzed in detail, and the targeted reinforcement measures are formulated, that is, the seepage control of the dam body and the dam foundation is carried out by the plastic concrete cutoff wall combined with the curtain grouting, which effectively solves the problem of seepage Problem, so that the reservoir flood control benefits to normal play, with some promotional value.
