Analysis of Tunnel Running through Bridge Pile Foundation Based on the MIDAS/GTS
Based on the problem of tunnel running through bridge pile foundation, a 3d numerical model is built by the finite element software MIDAS/GTS in order to research the internal force and the displacement of the pile and soil during the Construction process. The sedimentation value of the top of the pile is bigger than others. Because the bigger thrust about the Shield machine, the horizontal displacement of the pile is increasing at first and decreasing at last from a positive into a negative. Because of the loss of the soil, the soil beside the pile collapses and causes strong friction force. The surface sedimentation value which is near the central line of the tunnel is bigger than other place. This paper is of good reference roles in the similar underground engineering in Dalian.
