Numerical Simulation of Creep Deformation for Large Section Tunnel in Soil with Visco-Elastic-Plastic FEM

Abstract:

In order to reasonably analyze the influence of rheological properties on the soil deformation behavior of tunnel in soil, this paper establishes visco-elastic-plastic numerical calculation model for analysis of tunnel in soil deformation based on ANSYS software by relying on physical construction. The results show that creep deformation accounts for 24% of total deformation of the tunnel, so it is necessary to make visco-elasto-plastic analysis on tunnel in soil. If the numerical simulation results are basically the same with the trend of temporal curve of measured data, and the data obtained is relatively close, then the established model is correct.
