摘要
锚泊系统合理性、稳定性是保障浮标可靠性的关键因素。通过建立悬链线方程,推导出浮标锚链长度的计算方法,给出处于自悬链状态的临界值,通过锚系状态的判断以及锚驻力的计算分析锚泊稳定性。以长江口深水航道某水域航标设置情况为例,按此法对锚泊稳定性进行分析,并提出改变系泊方式、合理配置系链长度、增加锚驻力等措施增加浮标锚泊稳定性,为航标设计提供参考。
The rationality and stability of mooring system are the key factors to ensure the reliability of buoy.We establish the catenary equation to deduce the calculation method of buoy chain length,give the critical value in the state of nature catenary,and analyze the anchoring stability by judging the state of the anchor system and calculating the anchoring force.Taking the setting of buoy in the Yangtze Estuary deepwater channel as an example,we analyze the stability of the mooring by this method,and propose the measures of increasing the mooring stability of buoy such as changing the mooring mode,reasonably configuring the chain length,and increasing the anchor force.The results can provide the references for the design of buoy.
