摘　　要：简单评述了已有的极限载荷判定准则,并结合内压、拉伸和弯曲联合载荷下的管道应力情况,提出了一个确定联合载荷下塑性极限载荷的工程方法。Several available rules of the limit load were described briefly in the article. Based on the stress distribution of pipeline under internal pressure, tensile and bending load, an engineering method for defining actual plastic limit load under the combined loads is proposed.
