| 中文摘要: |
| 为了研究陆域回填对近岸段桩基的影响，结合鱼山大桥工程，分析鱼山围垦对鱼山大桥桩基的影响，利用ABAQUS软件采用三维固结有限元法进行固液耦合分析，考虑土体渗流以及地基和桥墩桩基础与土之间的相互作用。就堤后回填加载过程对鱼山大桥工程、地基和桥梁桩基的影响进行模拟研究，得出软基海堤与桥梁的相互作用情况下陆域回填对鱼山大桥的影响。结果表明，陆域回填会增加鱼山大桥的沉降和位移。 |

| 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. |
