摘要
在国内铁路隧道中,对地下水一般是以排为主,以堵为辅,造成了一定的负面影响。在歌乐山隧道,根据不同的地下出水情况,成功地建造了不同的止浆岩盘,运用帷幕注浆完成了隧道的堵水工作,减少了地下水的流失。帷幕注浆在隧道富水带是一种极其有效的施工方法,而止浆岩盘的成功与否是帷幕注浆的关键所在。该文为进一步推广这一技术提供了理论参考和实践经验。
Curtain grouting is an effective construction method in tunnel area with rich water. It is the key problem of curtain grouting whether we succeed in sealing batholite or not. In tunnel construction, for ground water, generally we give priority to drainage, and use plugging up as a complement. There is a certain side effect in this way. In the construction of Geleshan tunnel, according to the different conditions of ground water, we made different sealing batholite,and plugged up the ground water triumphantly with the method of curtain grouting. The paper is valuable both in theory and practice for the technique to be further promoted.
