海上风电单桩基础载荷影响因素研究

Influencing Factors on Monopile Foundation Load in Offshore Wind Farms

参照IEC61400-3标准,使用GH Bladed软件对福建浅水区域影响单桩基础载荷的因素进行多工况仿真计算分析表明,支撑结构的频率对基础载荷的影响较大,而塔架结构中的壁厚在一定的变化范围内对基础载荷的影响较低;基础极限载荷随极限风速增大而增大,而浅水区域极限海况对基础载荷的影响较小。

According to the IEC61400-3 standard,GH Bladed software is adopted to study the influencing factors on monopile foundation load in offshore wind farms in Fujian Province.Simulation results of various conditions show that the frequency of the supporting structure has a great influence to the foundation load,while the wall thickness of the tower structure within a certain variation range has a smaller influence.The ultimate foundation load increases with the increase of the extreme wind speed,while the extreme sea condition has less impact on the foundation load for shallow water areas.
