| Abstract | Taiwan area of about thirty-six thousand square kilometers long and narrow terrain, where the mountains and hills, representing approximately two-thirds of the Taiwan area, from the early manpower transportation to the power transportation to the present, the development of electric power transportation has also improved. Due to the mutual squeezing of the plates, the impact on Taiwan has formed an intricate geological structure, How to overcome complex geology to create a complete transportation hub network will be a big test. Deformation behavior and stress of surrounding rock mass during tunnel excavation, actually belongs to the three-dimensional type, for accurate analysis results, and understand the deformation behavior of the rock mass, it should start with three-dimensional numerical analysis and feedback analysis of monitoring point data. This study uses the FLAC^3D software program as an analysis tool., Refer to the excavation method of the snow mountain tunnel. Simulate dual main tunnels at different intervals (D=1/3B¦Ü2B) configuration, Carry out the excavation simulation of the intersection of the contact roads, Using three-dimensional values analysis result, Exploring the simulation and comparison of deformation and stress changes in different excavation stages, at the same time, it also simulates the excavation comparison of different soil depths. The results obtained provide a reference for the tunnel industry. |
