| Abstract: | Import section of Xiangjia tunnel lies in in weathered granite, where full of pore and fissure water , the surrounding rock is poor , groundwater recharge condition is complex, the tunnel water inrush possibility is very large. In this paper , regard a tunnel entrance to the V grade surrounding rock section as an example, the reinforcing ring of water inrush prediction and grouting tunnel V rock section is made. The research results will provide the technical support for the tunnel construction. |
