【摘要】 多筒基础平台是近年来在海洋工程中出现并得以迅速发展的一种新型结构形式.此种结构最大优势是便于安装,并能够自浮拖航运输,特别是在浅海区.为了研究不同的系拖点位置对结构拖航稳定性的影响,采用1∶20比例模型,通过模拟波浪作用,选取不同的系拖点位置进行试验,得到压力对比曲线及拖航力变化曲线.结果表明,系拖点的最佳位置是使拉力作用线通过或尽量接近结构浮心,而且要使拉力作用线与水平面夹角尽量小,这样可以最大程度上保证结构拖航的稳定性.更多还原

【Abstract】 Multi-bucket foundation platform is a new pattern structure used in offshore projects.The structure is convenient for installation and towing,especially in shallow sea.In order to study the effect of different towing points on stability of the structure in towing,model experiment with a scale of 1∶20 was carried out.The contrasting curves of pressure and the curves of pull in towing were obtained through the experiment in which the impact of ocean waves were simulated and different towing points were selected.The results indicate that the best towing point is to make the action line of pull get across or be close to the buoyant center of the structure,and the angle between action line of pull and horizontal plane should be small.So the stability of the structure can be ensured furthest.更多还原
