摘要
为了计算在深水环境下航标的活动范围,建立了航标锚泊系统的理论模型,并根据悬链线方程,推导了锚系在不同状态下航标活动范围的计算公式。针对深水环境下航标活动范围过大的问题,提出了航标双点系泊的方式,大大减小了航标的活动范围。结合一个实例,计算了航标在不同水深下的各个参数,计算结果满足工程的精度要求,表明该方法具有一定的工程参考价值。
To calculate the range of motion of navigation marks in the deep water, a theoretical model of navigation marks＇ mooring system is established and the formulas of navigation marks＇ range of motion in different mooring states are derived according to the cater nary equation. For the excessive range of motion of navigation mark in the deepwater environments, the two-point mooring mode of navigation marks is proposed, which reduces greatly the navigation marks＇ range of motion. This paper calculates various parameters of navigation marks in different water depths combining an example. The results meet the accuracy requirements of the project, and it indicates that the method has certain reference value in the engineering.
