Numerical Simulation Test of Tunnel's Deformation under Different Levels of Horizontal Stress
With the rapid development of tunnel construction, it is unavoidable that tunnel could go through deformation under complicated field stress. Under the action of tectonic stress, tunnel floors in sedimentary rocks are likely to succumb to deformation failure, which results from the complex stress environment. Tunnel excavation is simulated with ANSYS in different lateral pressure coefficient of in-situ stress. The distribution law of tunnel excavation section's deformation and plastic zone is analyzed. The experimental results show that the degree of damage to the roof and floor is greater than to the tunnel's sides with the increased horizontal stress. It is key to control the roof and floor of the tunnel under high levels of stress.
