摘　　要：针对天津港9～11段码头钢板桩接岸结构出现的锈蚀和破损现象,采用ANSYS有限元建立了钢板桩结构与土相互作用的数值计算模型,并进行了钢板桩在完好、锈蚀和局部破损3种情况下的有限元计算分析,得到了以上3种情况下的接岸结构及土体变形和钢板桩的受力状况。为钢板桩的安全性判定提供了依据。Aiming at the phenomenon of rust and damage in the link-banked structure of 9-11 sections in Tianjin Port,a numerical calculation model concerning the interaction between the steel sheet pile and the earth was established using the ANSYS FEM model.Besides,the FEM analyses of the steel sheet pile being in good condition, rusted and partial damaged were carried out.As a result, the deformation of the link-banked structure and the earth and the force of the steel sheet pile were obtained, which provided the reference for security decision of the steel sheet pile.
