The Dynamic Response of Tunnel through the Karst Cave under Impact Load
More and more construction of tunnel engineering in karst region. Karst influence on tunnel engineering in deformation and instability, it often leading to Partial collapse, impellers, rock fall in the tunnel excavation or after work. For through large Karst cave tunnel, it will give great harm to tunnel, adjacent structures and injuries and consequence is very serious when faced with karst collapse occurs. The paper is based on engineering example of XieGiadong cave tunnel, the research results has important value for engineering construction and protection of resources. For example, the tunnel lining structure under the action of impact load produced large deformation and the overall shear failure and the process is ephemeral. Tunnel in the process of impact contact to destroy only less than 0.1 S, The vertical displacement of 2.88 m, the horizontal displacement of 0.8 m, fall since the collapse of rock mass to the maximum contact force of the contact with the tunnel 7000000KN.
