悬浮段海缆的结构以及运动情况最容易受到海洋水文条件的影响,过大的载荷会对水下电缆悬浮段结构造成严重安全隐患甚至断裂.通过对悬浮段海缆在不同环境条件下所受的环境载荷进行建模分析发现,随着潮流流速增大,悬浮段水下电缆存在对应的位移与受力情况,对此,提出了海缆套管、砼联锁排压覆等相对应的保护措施.
Load Analysis and Protection of Submarine Cable in Suspension Section
With the continuous development and utilization of ocean energy to the deep sea,the application scenarios of underwater cables will be more extensive,and the environmental conditions will be more complex.The structure and motion of submarine cable of the floating section are vulnerable to the influence of Marine hydrological conditions.Excessive load will cause serious safety risks to the structure of submarine cable of the floating section and even break the cable.In this paper,modeling and analysis of environmental loads on floating submarine cable under different environmental conditions are carried out.It is found that with the increase of current velocity,there are corresponding displacement and stress conditions of floating submarine cable.The corresponding protection measures are put forward as well.
