Abstract: When a shield tunnel passes bridge piles on the side in proximity, vertical and horizontal deformation can be caused in the piles. Therefore, it is necessary to study the deformation law of bridge piles under such circumstances. Method: A numerical calculation model is established and validated for reliability. The horizontal deformation and settlement of eight piles are analyzed. Based on the numerical calculation model, the xdirection horizontal deformation, ydirection horizontal deformation, and settlement of each pile during shield tunneling are analyzed. The influencing factors of shield tunneling pile xdirection horizontal deformation is investigated. The impact of shield tunneling on the actual settlement of each pile is compared and analyzed. Result & Conclusion: The No.1 pile that is closest to leftline shield tunnel demonstrates the largest settlement, while the settlements of piles No.2 to No.8 are significantly smaller than that of pile No.1. The disturbance caused by rightline shield tunneling had a minor impact on the piles farther away from the rightline shield tunnel. Shield tunnel sidepassing bridge foundation has the most significant impact on pile horizontal xdirection deformation. As the shield tunnel diameter increases, the pile maximum horizontal deformation gradually increases. As the tunnel buried depth increases, the pile maximum xdirection horizontal deformation initially increases and then gradually decreases. The shield tunnel sidepassing process will lead to evident settlement of pile foundation, and after passing through the soil, the negative skin friction would disappear, resulting in a certain amount of rebound in the piles.
