摘　　要：张力腿平台是一种典型的深水采油平台,其优良的运动性能得到了业内的认可。针对一座传统式张力腿平台进行了数值模拟和分析,得到平台的动态响应。对极端工况下平台筋腱不同的刚度、布置角度、预张力和筋腱数目进行了计算和对比,得到了系泊筋腱受力以及平台位移的时历曲线。通过数据的分析得到了一些在实际工程应用中有用的结论。As a typical oil production platform in deep-water, tension leg platform has excellent dynamic performance. This paper presents numerical simulation of a conventional tension leg platform in deep-water. Dynamic response of the platform is calculated with the coupled analysis in time domain considering both the platform and the mooring system. A comparison of results among different stiffness, different arrangement angles, different pretension and the different number of legs is carried out, while the tension of mooring system and time history of the dynamic response of the platform is obtained. These results may be helpful in oractical engineering aoDlication.
