摘　　要：在深入剖析钢板桩接岸结构破损机理的基础上,提出了3种加固方案,即帽板加固法、局部外包法和地连墙替代法。通过有限元分析软件ANSYS建立了有限元模型,分别对接岸结构及土体变形特征和钢板桩等结构的受力进行了分析,并对3种加固方案的施工可行性进行了比较。最终确定局部外包法为最终加固方案。Based on the damage mechanism of link-banked structure of steel sheet pile,three reinforcement methods such as cap reinforcement,local reinforcement and diaphragm wall reinforcement were proposed in this paper.A finite element model was established with the finite element analysis software ANSYS to analyze the forces acted on steel sheet piles and the deformation characteristics of soil and link-banked structures,and the construction feasibility of the three reinforcement methods were compared.Finally,the local reinforcement is chosen as the final scheme.
