摘要
隧洞施工中,出现较大的裂隙饱和水时,将影响隧洞的正常施工,造成隧洞围岩失稳,产生安全隐患。通过对裂隙饱和水的成因分析,选择超前注浆施工方法,对裂隙饱和水进行封堵。通过注浆效果检验分析,表明超前注浆法对裂隙超饱和水防治效果良好。
In the tunnel construction, there is a large amount of saturated fissure water;it will affect the normal construction of the tunnel, causing the surrounding rock instability, resulting in a safety hazard. Through the analysis of the causes of the saturated fissure water, the method of pregrouting construction is chosen, and the sealing of the saturated fissure water is carried out. Through the analysis of the effect of grouting, the results show that the method of pre grouting has a good effect on the prevention and cure effect of the crack.
