The Karst development characteristics and countermeasure of Yunwushan Tunnel

The paper introduced main problems of engineering geology and hydrogeology of Yunwushan tunnel, and put forward a construction scheme which can prevent geological hazards.

Yunwushan tunnel of Yichang-Wanzhou railway is one of the eight high-risk of the tunnel, the tunnel during the construction process revealed a number of large-scale karst.

The basic method for hydrogeological research and flowing yield forecast is introduced according to Qingyunshan tunnel.
