摘　　要：为研究斜向流对锚链线的影响,进行深水锚泊船锚链线静力分析与计算。推导出三维锚链线微分方程,定义了方程中的2个单位矢量,并明确了该微分方程的物理含义。模拟计算表明,在深水条件下,锚链线具有三维曲线特征,与相同流速的二维锚链线相比,其主要差别在于侧向弯曲。For studying the influence of oblique current on mooring line, analysis and computation of the static characteristics of anchoring line in deep water are carried out. Differential equations for the three-dimensional（3D） mooring line are set up. In the differential equations two unit vectors are defined and their physical significances are ex- plained. Simulation results show that the anchoring line in deep water condition has distinctly the features of 3D curved line. Compared with the 2D mooring line in the same condition of current speed, the main difference is that 3- D mooring line has lateral bending.
