| 摘 要： | 我国混凝土结构设计规范（GBJ－89）对先张法预应力混凝土构件进行蒸汽养护时的温差损失，有明确的计算方法。从考虑钢筋和混凝土之间的线温度膨胀系数关系入手，对该项损失提出了不同的看法，供参考讨论。

| Abstract: | About prestress loss in temperature due to steam curing in pretension concrete, there is special regulations in our concrete code of structural design(GBJ-89). We come up with a different theory to prestress loss in temperature according to linear termal expansion coefficient of steel and concrete , which can be used to further discussed. |

| Keywords: | pretension concrete linear temperature coefficient restress loss in temperature |
