| 摘 要： | 建立了锚泊线与海底接触的模型,计算了水中锚泊线的空间形态和应力分布数值,分析了锚泊线动力和导缆孔的应力变化状况。采用弹塑性的土本构模型对海底基础建模,分析了锚泊线与海底有无摩擦情况下的应力和变形,为锚泊线的设计提供新的分析方法。

| Abstract: | A mooring line and seabed interaction finite element model is built.Geometry and stress of a mooring line are also computed.Tensions and offset of the fairlead point are analyzed,taking account of the friction between the contact of line and seabed.A few results are drawn for the mooring line design |
| |
| Keywords: | mooring line dynamics seabed interaction soil constitutive model |
