Study on Mechanical Properties of Compound-Umbrella Arch in Bias Tunnel Entrance
For a comprehensive analysis of the mechanical properties of compound-umbrella arch in the unsymmetrically loaded tunnel entrance, we focus on the force characteristics to optimize the structure of composite umbrella arch, and improve its economic efficiency. The stresses on the bottom of pile, the pile and the steel arch were monitored, and analyzed by the finite element software. The results show that, on the bias terrain, the stress of the pile bottom is nonuniform with uneven settlement. The stress distribution is very complex, where the tensile stress appears on the pile bottom, the compressive stress takes place on the arch foot and the vault, which is not good to the stability of the overall umbrella arch. As both sides of the umbrella arch bear a large different force, the piles on both sides of the umbrella arch subject to large bending moment and axial force, which improve the stability of the tunnel entrance.
