In this paper the different middle wall s mechanical behavior on different rock mass has been simulated by establishing the three-dimensional finite-element model of the shallow double-linked-arch tunnel,and the basic loading law of the middle wall is obtained,then the proper form of mi.

How to reveal the idea to protect surrounding rock in deep-buried tunnel construction

Because of complex tectonic boundary condition and high stress environment in deep rock mass,surrounding rock has intrinsic characteristics,which will damage caused by stress redistribution in excavation of deep-buried tunnel.
