摘　　要：某填海工程的实施可能影响邻近桥梁的安全性,拟采用斜撑钢管板桩直立式海堤结构,通过Plaxis 3D岩土有限元分析软件模拟该海堤结构的受力特性及变位,以及其对邻近桥梁桩基变位的影响。结果表明,该直立式海堤结构受力特性较好、变位较小,且对邻近桥梁桩基变位的影响较小。The implementation of a reclamation project may affect the safety of the adjacent bridge,so it is proposed to adopt the vertical seawall structure with inclined steel pipe and sheet pile.The force characteristics and displacement of the vertical seawall structure,as well as its influence on the displacement of the pile foundation of the adjacent bridge,are simulated by Plaxis 3D geotechnical finite element analysis software.The results show that the vertical seawall structure has better force characteristics and less displacement,and has little influence on the displacement of adjacent bridge pile foundation.
