The total vertical displacement produced by creep is small, thus creep displacement can not affect the running safety of dam.
由蠕变产生的总的垂向位移不大，在安全范围内，因此蠕变位移不会影响大坝的使用安全；

With the time being separated into some periods, the prestressing loss in each period due to shrink, creep and relaxation is calculated, and then the total loss obtained.
该法把时间分割为若干时间段，求解各段因收缩、徐变和松弛引起的预应力损失，并叠加求总损失。

According to the total strain energy failure theory author provides calculate formula of creep Life loss in creep deformation accumulation of steam pipe.
