Abstract:
Based on the Qiliping Tunnel on the Yongzhou to Liuzhou section of the reconstructed Hunan-Guangxi Railway, the bolt supporting program of the Qiliping Tunnel was optimized using the three-dimensional discrete element software 3DEC, taking into account the geological characteristics and forces of the surrounding rock as well as the support measures of shallow bias tunnels.
