摘　　要：将蠕变损伤法与传统方法(持久强度法)作了比较,指出了传统方法存在的问题,深入讨论了蠕变损伤法在高温管道的寿命评估中的优越性。结果表明:相对于持久强度法,用蠕变损伤法测得的高温管道的断裂寿命可靠性更高。and traditional cussed deeply. Creep damage method and traditional method （high temperature method＂ s problems are The result is that creep pointed out in this paper. The superiority strength of creep method） are compared, damage method is disdamage method is more reliable than high temperature strength method.

关 键 词：持久强度 蠕变损伤 寿命优越性
