摘要
鉴于目前海上风机的安装主要借助自升式风电安装平台,为保证自升式风电安装平台吊装的安全性,开展平台插桩入泥深度的计算方法研究。考虑到相邻土层的影响,提出海底多层土极限承载能力的计算方法,并将其与实际施工记录及有限元分析结果相对比,验证该方法的准确性,为海上风电装备的施工提供参考。
Considering the fact that majority of offshore wind turbines are installed by jack-up platforms, studies are carried out on the calculation method of platform leg mud penetration depth to ensure the safety of jack-up wind turbine installation platform. Then the method for calculation of the ultimate bearing capacity of multi-layered soil at sea bottom is proposed, taking into account the influence of the surrounding soil layers. The accuracy of the method is validated through the comparison between construction data and finite element result. The method provides reference for the installation operation of offshore wind turbines.
