摘要：Based on the rail transit of Xuzhou city and considering the actual engineering geological conditions, this paper studies the deformation effect of bridge piles across the railway bridge of shield tunnel. In this paper, the finite element numerical analysis software Midas GTS/NX is used to analyze the influence of the shield tunnel crossing bridge on the deformation of the bridge pile, and the change law of the displacement of the bridge pile under the condition of unreinforcement and reinforcement is obtained. The calculated results show that under the condition of no reinforcement, the settlement deformation of the bridge pile exceeds its own displacement limit due to the side crossing of shield tunnel. The reinforcement scheme of the bridge pile is used to enlarge the size of the original bearing platform section and add the foundation pile, and the simulation is carried out. The results show that the settlement of the bridge pile decreases significantly under the condition of reinforcement. The results prove the rationality of the reinforcement scheme to a certain extent, and provide a certain theoretical basis for the design of similar shield tunnel lateral pier pile.
