摘　　要：提出了海上浮动软管的三维静态分析模型。在四级海情下,对输送柴油的软管求得了解析解,得出了软管在侧向和垂直方向的偏移及其所受的拉力,认为此时的软管是不安全的。The hosestring system floating on sea bears complicated forces in a multidimension force field. It is difficult to get the accurate solution of this system. With some basic suppositions and reasonable simplification, a threedimension analysis model of the hosestring is introduced in this paper. Under the 4th sea condition, the numerical solution of the hosestring transporting diesel oil is obtained. Also,the deflection of the hosestring in lateral and vertical directions and the tension force the hosestring bears are gained. It is unsafe for the hosestring under this condition according to the solution. The work described in this paper offers a theoretic basis for designing the hosestring system.
