Construction Treatment Measures to Qi-yueshan Tunnel in Typical Karst Area

The Qi-yueshan tunnel project is located in the area of typical karst, the entrance section construction of which faces the most difficulty. Aiming this point, the author introduced the geology and hydrology conditions of the entrance section and the content of geology forecast. Furthermore, the project geology and hydrology were analyzed, and treatment measures to typical karst such as intermittent and water bursting type, filling type, etc. were put forward. These measures have accumulated the construction experience for similar problems in the future.
