摘　　要：对适用于球壳大开孔接管结构的补强设计方法进行了比较评议,并对一系列的大开孔模型分别采用压力面积法和极限分析设计方法进行了补强,通过分析补强后的结构可知,按照我国JB4732规范进行大开孔接管结构补强,其安全裕度更高.Reinforcement designs of spherical shell with big nozzle were observed on. With method of pressure area and limit analysis, a series of models were reinforced, and by analyze theses reinforced models, acon-elusion was brought out that the safty factor is bigger than others if the reinforcemnet is designed by JB4732-1995 'Steel Pressure Vessels-Design by Analysis'.
