使用SACS软件，考虑桩-土非线性，建立了海上电气平台整体结构有限元分析模型。基于不同荷载作用方向作用，开展了八组极端工况和四组正常使用工况下电气平台的有限元分析。依据有限元分析结果对电气平台进行了杆件应力、节点冲剪以及地基承载力校核。同时开展了电气平台动力特性分析，以及地震反应谱分析。

The finite element model of offshore substation platform is established based on SACS software and considering the nonlinear interaction between piles and soil. The responses of offshore substation platform under eight ultimate limit states and four normal limit states are analyzed subjected to the loadings in different direction. Based on the results of finite element analysis, the stress of rods, the shear force of nodes and the bearing capacity of foundation are checked. The dynamic characteristics and earthquake responses of offshore substation platform are also studied.
