一种抛锚出链长度的计算方法

Calculating method for length of let go chain when dropping anchor and its application

通过锚泊工况下锚链的受力分析，给出抛锚出链长度和落锚点的一般计算公式．并通过模拟计算，得出当风力超过１０ 级时，为防止船舶走锚，须改单锚泊为双锚泊．

By analyzing the forces of the chain when anchoring, the paper gives out the calculating formulas for the length of let go chain and the dropping point. By the modulated calculations, it proves that double anchoring must be adopted instead of single anchoring to avoid the ship's dragging if the force of wind exceeds 10.It has had good results in practice.
