Abstract: In this study, a two-span continuous beam bridge is used as the model to calculate the theoretical solution of the lateral collision between the main beam and the retaining block under the vertical separation of the main beam and the bent cap, and the most unfavorable separation condition for the analysis is selected. The impact of the vertical separation of the bridge on the impact of the block is verified by calculating the lateral collision force of the block when the main beam and bent cap are separated. We calculate the changes in the vertical positions of the main beam and pier under multiple separation collision processes and select two characteristic parameters, the collision force and the collision position. According to the specifications, the impact of the structural collision caused by the separation conditions on the failure mode of the block is verified.
