摘　　要：本文通过理论分析了压力容器封头超标大开孔的可行性及安全性，并用实验手段验证了这种结构的安全可靠性。该结构经过适当补强后是安全的，在国内外均有应用实例。The feasibility and safety of over code openings of pressure vessel covers were proposed through theoretical analyses,and the reliability of the structure was verified by using experiments. The authors considered that the structure was safe with suitable excess weld metal,there were application practices at home and abroad,and the structure was perspective.
