- Abstract
The fault is often encountered in tunnel engineering. To reveal the mechanical response characteristics of the tunnel surrounding rock during construction near the fault, according to the actual trend of the fault and the different angles between the fault surface and the axis of the tunnel, the whole process of tunnel excavation was simulated by using MIDAS/GTS software. The deformation and failure characteristics of the surrounding rock in different sections were analyzed and the support strength was also analyzed. Results show that the bench excavation is better applied to the current geological characteristics, and the support strength can ensure the long-term stability of the surrounding rock of the tunnel. The construction excavation will cause some surface subsidence, but the subsidence is small. According to the design and a double-layer reinforcement network support strength, the excavation demand of the tunnel can be met. The qualitative and quantitative results are mutually verified and comprehensively judged to escort the construction process. The conclusions obtained in the study provide a significant reference to the tunnel construction near the fault.
