| 摘 要： | 为了从定量上掌握锚泊船卧底锚链的长度 ,保证锚泊安全 ,本文根据锚链悬链线特殊性质 ,提出了在出链长度一定的情况下估算卧底链长的一种简易方法 ,即根据锚链在锚链筒外孔处与铅垂线的夹角来估算卧底链长的方法 ,并对估算误差作了简要分析。分析表明 ,当锚链张角 <5 0°时 ,误差较小 ;当锚链张角 >6 0°时 ,误差偏大 ,但仍可满足航海实践需要

| Abstract: | In order to know the length of chain cable lied on seabed and to ensure the safety of anchoring ship, a simple method to estimate the length is presented in the paper with catenary characteristics and the angle between the cable and the perpendicular at hawse pipe and the errors of estimation is also analyzed. It is showed by analysis that the error is smaller when the angle is less than 50 degrees and bigger when the angle is greater than 60 degrees, even so this method still can meet nautical requirements. |
