In order to analyze the mechanical properties parameters sensitivity of large section soil tunnel, this paper designs numerical test program of the degree of influence on mechanical properties by the change of physical and mechanical quantities based on the orthogonal experiment design. Depending on two-dimensional elastic-plastic finite element method, in this paper, multiple loading conditions numerical simulation has been carried out to level V wall rock large section tunnel in soil through double side drift construction method, and according to the numerical simulation results, the sensitivity extent wall rock parameters to the tunnel mechanical properties and stability, which may provide a basis for large section tunnel design calculation and construction.
