摘　　要：以TLP海上风机为研究对象,结合黄海海域环境条件对张力腿风机基础的水动力响应进行模拟分析。在计算过程中,风荷载分为作用在塔柱上的风荷载和风机荷载两部分,采用高阶边界元法建立数值模型,开发了风、浪、流耦合作用时域程序。针对不同风、浪、流入射工况进行模拟,计算结果表明,风荷载单独作用下张力腿风机结构产生的运动响应与波流力作用下响应值比较不可忽略,并得到了一些对工程实践有意义的结论。This paper uses a TLP wind turbine as the research object, combined with ocean environment of the Huanghai, the motion responses of the TLP platform interaction with wind-wave-current are investigated. In the process of calculation, the wind force can be divided into two parts, which are the wind turbine load and the wind load actions on the pylon. A higher-order boundary element method is used for establishing numerical model. The time-do-main program is developed to simulate the interaction of wind-wave-current with offshore plat- form. Different incident conditions of wind-wave-current are simulated, the ealeulation results show that the motion response of TLP platform induced by wind load is equally significant to the wave-current load. Some conclusions helpful to engineering practice are obtained.
