摘　　要：提出了钢悬链式立管与浮式平台整体分析模型,将SCR和浮式平台作为一个系统进行整体分析,基于Cable3D程序开发出整体分析程序,并分别采用耦合法和整体分析方法分析了浮式平台作用下的SCR的运动响应及SCR对平台运动的影响,研究表明,整体分析方法可以很好的反映结构之间的动力效应,立管系统对平台的运动的响应幅值有一定影响。A model for a SCR and a floating platform to be treated as an integral system was proposed here. A computer code was developed based on the cable dynamic analysis program CABLE3D. The motion response of the SCR under the action of the floating platform and its effects on the motion of the platform were calculated using both the coupled method and the integrated analysis method in time domain. The results showed that the integrated model factually reflects dynamic effects between the SCR and the floating platform, and the SCR has a certain effect on the response amplitude of the platform.
