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.
