摘　　要：由于含体积型缺陷压力容器和管道结构及载荷条件的复杂性,往往很难找到它们极限载荷的解析解,因此其研究重点转向切实可行、计算效率高的数值方法。综述了国内外结构极限分析数值方法的研究现状,重点分析了目前国内外含体积型缺陷压力容器和管道极限分析的研究现状,对今后含体积型缺陷压力容器和管道的极限分析具有一定的指导作用。The analytical solutions for the limit analysis of pressure vessels and pipelines with volumetrical defects are very difficult to find because of the complexities of their structures and load conditions. So,people put the research emphasis upon the feasible and efficient numerical methods. The paper summarizes the current research situations for the structural limit analysis numerical methods and emphatically analyzes the current research situations for the limit analysis of pressure vessels and pipelines with volumetrical defects at home and abroad. The research results will be important and useful for guiding the limit analysis of pressure vessels and pipelines with volumetrical defects.
