Study on Numerical Simulation of Construction Processing for No.1 Shaft of Weihe Tunnel

Abstract:

In order to analyze the construction processing for No.1 shaft of Weihe Tunnel on Baoji-Lanzhou Passenger-dedicated Railway, a two-dimensional numerical model for the simulation of the shaft was built with the finite difference method. Mohr-Coulomb model was chosen as the soil constitutive model. The result shows that the maximum lateral displacement appears at the upper part of the shaft, and the lateral displacement is in effective constraint at the shaft’s bottom. After the construction, the maximum uplift at the shaft’s bottom is in the center, while the uplift decreases from the shaft’s center to its both sides. The maximum pressure stress turns up at the bottom sides of the shaft, and the maximum tensile stress appears at the middle of the shaft.
