New Computation Method of Suspension Chain and Stability Analysis of Single Anchorage in Port

介绍一种悬链静力计算的新方法。它是利用直角坐标系,从悬链基本方法出发,推导并建立悬链几何、力学为特征的计算式,同时还给出自悬链和约束链链型的判别式。在锚泊过程中,锚驻力是决定锚泊稳定平衡的关键条件。文中例举了两种不同系泊力,计算悬链几何、力学诸参数,并说明锚泊稳定或不稳定的计算结果。

This paper introduces a new method of statical computation of suspension chain, which adopts rectangular coordinate system to derive and establish the computation formulae characterized by suspension chain geometry and mechanics based on the basic computation method of suspension chain, and provides the discriminants for self-suspending chain or restricted chain. In the process of anchorage, anchoring force is the crucial condition of anchorage stability equilibrium. Two different kinds of mooring forces are listed to calculate geometrical and mechanical parameters of suspension chain, and the computation results under the conditions of stable anchorage and unstable anchorage respectively are explained.
