摘　　要：本文提供一种使用GHS软件求解FPSO坞墩支反力的新计算方法。经过迭代计算多种吃水状态下的坞墩支反力情况,绘制出支反力曲线图,直观的反映出整体坞墩和关键区域坞墩受力情况,计算结果更加趋近真实。为大型海工项目精准布置坞墩、提前排查隐患提供科学依据,为进出坞配载提供技术支持。This paper provides a more scientific calculation method to solve the dock block reaction force of FPSO by using GHS software.The reaction force under various draft conditions is calculated iteratively,thus the reaction force curve is plotted,intuitively reflects the force situation of the dock block as a whole and the key area of the dock block,and the calculation results are more realistic.It provides scientific basis for the accurate dock block layout,the investigation of hidden risks in advance for large offshore projects,and provides technical support for loading in and out of dock.
