摘要
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,在时域内对不同风、浪、流入射工况下张力腿平台风机支撑结构的水动力特性进行研究。计算结果表明:风荷载对张力腿风机结构的作用力与波、流作用力同样显著,风、浪、流耦合荷载最大值大于波流力最大值,以风荷载为主要荷载进行风浪流组合得到的计算结果偏安全。
The hydrodynamic characteristic of offshore TLP-type wind turbine foundation under different wind-wave-current conditions are studied, in which, a higher-order boundary element method is used for establishing numerical model and the time- domain program is developed to simulate the interaction of wind-wave-current with offshore platform. The calculation results show that the wind load is equally significant to the wave-current load interaction on TLP platform, the coupled load of wind-wave- current is larger than that without wind, and the simulated result of wind-wave-current interaction with TLP platform are more safe when taking the wind load as major load.
