摘　　要：为比对分段建模与整体建模工作量及稳性计算结果,选取某浮船坞,采用命令流方法,对坞墙无开口,做5分段建模和整体建模稳性计算,对坞墙有开口,做7分段建模和借助体过渡整体建模稳性计算,结果表明,无论坞墙有无开口,整体建模比分段建模节省约一半工作量,两种建模方式稳性计算精度相同,建模过程表明,命令流方法整体建模计算稳性,高效快捷。In order to compare workload and accuracy between subsection modeling and holistic modeling of stability analysis,3D modeling and stability analysis were carried out for a real floating dock.For dock wall with no opening,5 subsections modeling and holistic modeling were built by using the command method;and for dock wall with 4 openings,7 subsections modeling and holistic modeling were built by body transition.It was shown that compared with subsection modeling,the holistic modeling saves about half of the workload,no matter what dock wall with or without openings;both modeling methods have the same stability analysis accuracy.The holistic modeling by command flow method is quick and efficient for stability analysis.
