游艇码头拉簧式锚碇结构设计方法

Design method of spring anchorage structure for marinas

我国现行规范中,对游艇码头拉簧式锚碇结构没有提出明确的设计方法。简要介绍游艇码头拉簧锚碇结构形式及其原理,对拉簧锚碇结构的优缺点进行分析;结合游艇码头的使用要求,提出一种拉簧锚碇系统的布置方式,并对拉簧长度的计算提出要求。由于拉簧式锚碇系统结构计算的复杂性,其难以简化为二维问题手算得出结论,宜采用三维有限元分析方法。提出一种简化算法,使拉簧式锚碇系统所受竖向荷载的计算实现自平衡。

In the current Chinese code,design methods are lacking in spring anchorage structures for marinas.We briefly introduce the style and principle of the spring anchorage structures and analyze their advantages and disadvantages.Based on the operating requirements of marinas,we propose a layout pattern of spring anchorage systems and raise the requirements for spring length calculation.Due to the complex structural calculation of the systems,it is difficult to simplify the calculation into a two-dimensional problem and draw conclusions by hand calculation.The 3D finite element method is appropriate.A simplified calculation method is proposed,which can realize the self-balance of vertical load calculation for spring anchorage systems.
