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 wa-ter 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.
