| Abstract: | Combining with project cases,and using nolinear finite element software,the analog computations are made for the excavation and shoring of the granite tunel in deep and high crustal stress,the surrounding rock stability and internal force of supporting structure in the time of construction,working and service are analyzed respectively,and the results of surrounding rock deformation and forcing of supporting structures in above working conditions are given.Meanwhile,the optimizing calculation of supporting structures is proceeded,and the safety requires for rock structure stability and supporting structures under optimization are obtained. |
