单柱复合筒型基础结合了单桩基础与筒型基础的优点,能有效缩短施工期、降低成本且对环境友好.拖航是单柱复合筒型基础可重复利用、便于运输和安装的关键技术,需对拖航性能进行深入研究,为实际拖航过程提供技术指导.使用MOSES软件建立单柱复合筒型基础水动力模型,对单柱复合筒型基础的拖航过程进行数值模拟.计算结果表明,单柱复合筒型基础拖航性能较好,其运动响应受波浪和浮运条件影响显著,应避免横浪和大浪,且不宜在波浪周期接近基础固有周期时段拖航;通过调整系缆点高度、吃水深度及拖航速度可提升结构拖航稳性.
Investigation into the towing performance of single-column composite bucket foundations
The single-column composite bucket foundation is a promising solution that combines the benefits of single-column and bucket foundations.It offers advantages such as reduced construction time and cost,as well as environmental friendliness.Towing plays a crucial role in enabling the reusability,transportability,and ease of installation of single-column composite bucket foundations.Therefore,it is essential to thoroughly investigate the towing characteristics of this foundation type to provide technical guidance for the actual towing process.In this study,numerical simulations of the single-column composite bucket foundation were conducted using MOSES software.The simulation results demonstrate that the single-column composite bucket foundation exhibits favorable towing performance.Its motion response is significantly influenced by wave and floating conditions,with the need to avoid cross waves and large waves.Towing should also be avoided when the wave period is close to the foundation's inherent period.Furthermore,adjusting the height of the towing point,draft depth,and towing speed enhances the towing stability of the structure.
