摘　　要： 本文采用半确定性法进行了导管架装驳运输分析。在计算驳船运动时,考虑到驳船的长度与宽度之比、吃水与宽度之比都很小,三维影响严重,故本文采用了纵横切片的思想,配以经验性的三维修正。在校核导管架的强度时,忽略了驳船结构的弹性影响,根据驳船运动诱导的惯性力,以及风力、重力等求出导管架各构件的应力,然后按AlSC规范及API规范进行校核。本方法已编制成计算程序,并对渤海油田系船导管架进行了装驳运输实例计算。 This paper deals with the analysis of barge-jackel assembly during transportation using semi-determinastic method. Because the proportions of length to breadth and draft to breadth of barge are quite small,the three dimentional effect on the motion exists seriously. For this reason in the calculation of the motion of barge the transverse-longitudinal strip theory is used in coordination with the practical three dimentional correction. In the strength analysis of the jacket the stresses of menbers are calculated according to the wind forces, gravity forces and inertia forces induced by the motion of the barge, then checked in accordance with the criterion of AISC regulations and API Rules. The computer program has been developed for the proposed method and an example of strength analysis of a mooring jacket, used in Bohai oil fields loaded on a barge during transportation is also carried out.
