Simulation and analysis of surrounding rock deformation during construction of water-rich soft rock tunnels
Due to its complex geological conditions, the water-rich soft rock tunnel will encounter many troubles in the construction process, among which the deformation of surrounding rock has a great impact on the project, and if it is not properly handled, it is likely to lead to serious construction accidents such as tunnel collapse, so it is necessary to analyze the deformation of the rich water rock tunnel. This paper adopts the finite element simulation method and establishes a planar model to simulate the tunnel construction and the deformation process of surrounding rock. The orthogonal experimental design with three factors and three levels is used to simulate nine different working conditions, and the deformation values of vault settlement and arch waist convergence were selected as the observation indexes of the experimental results. The results of the study show that the lower the shear strength of the surrounding rock, the higher the permeability coefficient and the higher its deformation after the excavation method is determined.
