Abstract

Research on the deformation and failure of surrounding rock is very important to the excavation of tunnel, in this paper, based on the geological data and mining conditions of a tunnel engineering using the finite element software FLAC3D to simulate the process of tunnel excavation, and the failure characteristics of surrounding rock under the action of mining is analyzed. In order to better analyze the rule of vertical displacement after tunnel excavation, some nodes of the vault and bottom of the tunnel are selected to monitor the vertical displacement, and the results of numerical simulation are close to the measured values. Providing effective theoretical support for the safety construction of tunnel engineering.
