Abstract

The ABAQUS software was used to establish a finite element model of the existing bridge piles for curved shield tunneling, and the impact of each stage of curved shield tunneling construction on the upper surface and adjacent pile foundations was analyzed. Research has shown that the main settlement of shield tunneling occurs during the shield tunneling stage and the detachment stage of the shield tail, with the maximum surface settlement located on the inner side of the curved shield tunneling; The horizontal displacement deformation of the pile foundation is the largest within the scope of the shield tunnel; The maximum vertical deformation of the pile is located at the top of the pile, and the magnitude of the vertical settlement of the pile is related to the horizontal net distance between the pile and the shield tunnel. A smaller horizontal distance will result in larger vertical settlement.
