中文摘要：
针对典型的TLP平台，考虑张力腿与桩基础的耦合效应，建立张力腿平台在波流联合作用下的动力响应分析模型。采用势流理论计算平台的水动力性能、一阶波浪力及二阶和／差频波浪力传递函数。在极端海况下计算并分析TLP平台的动力响应；将刚性基础及不同桩径、埋深长度组合时的弹性基础进行对比，研究弹性基础对TLP平台动力特性的影响。通过分析得到一些对实际工程有指导作用的结论。
英文摘要：
A dynamic model of TLP under the action of wave and current is established with the consideration of coupling between tension leg and foundation. Hydrodynamic performance of the platform, transfer functions of first-order wave frequency force, second-order wave force and sum/difference frequency forces are calculated based on potential theory. Dynamic response of TLP is predicted at extreme condition, and influence of foundation on dynamic characteristics of the platform is studied through a comparison of the results obtained by rigid foundation and elastic foundation with different pile diameter and length. Through data analysis, some useful guidance on practical projects is reached.
