摘　　要：三通几何结构和受载较复杂,是管系中的薄弱环节,准确预测三通的塑性极限载荷,成为管道完整性评估的关键技术。综述了国内外三通塑性极限载荷的研究现状,对今后三通塑性极限载荷的研究和安全评定标准的制定具有一定的指导意义。In view of complicated geometrical structure and loading, pipe branch is a weak part in piping system. It is essential for pipe integrity assessment to predict correctly the plastic limit load of pipe branch. The current research situation of plastic limit load of pipe branch at home and abroad was summarized in this paper, which can be referenced in further research of plastic limit load of pipe branch and establishing of safety assessment standard.
