Abstract

The displacements and geometry of the rock blocks and the properties of the rock structure play an important role in the stability of tunnels. Based on the key block model, the dynamic instability analysis of underground tunnel subjected to intensive short-time compressional wave was conducted. The instability of the tunnel caused by the spallation and the inertial effect was distinguished. And the influence of the roof contour curvature of tunnel was also determined.
