To study the influence of backfilling to the pile of the bridge near the shore side，we analyze the interaction of the Yushan reclamation and the pile foundation of the Yushan Bridge combining with the actual project，use the three-dimensional consolidation finite element method by ABAQUS to carry out the solid-liquid coupling analysis considering the soil seepage and the interaction of foundation，bridge pier pile foundation，and soil，simulate the process of backfilling and its influence to the bridge approach，foundation and bridge pile of the Yushan Bridge，and obtain the influence of land backfill on the Yushan Bridge under the interaction of soft foundation seawall and bridge.The results show that land backfillcan increase the settlement and displacement of the Yushan Bridge.
