Boundary Selection in Numerical Simulation of Deformation Stability of Soft Argillaceous Shale Tunnel
Based on the excavation and support construction of an engineering case in Zhongshan tunnel, located in the Changzhang Freeway of Hunan province of China, the boundary selection during the numerical simulation of deformation stability in soft argillaceous shale tunnel is studied. The FLAC 3D is used to simulate the full construction process, in order to analyze the influence of boundary effect to the solution precision in modeling. Under the same condition of other factors, different model boundary areas are simulated independently. The influence of boundary areas to the precision of tunnel excavation modeling can be analyzed by comparing the mechanical responses of different models in the same section. The research methods and conclusions can be a reference for similar numerical models of how to select reasonable model boundary area, therefore the timeliness and precision can achieve a better integration in simulating process in further researches.
