| 摘 要： | 核反应堆安全壳预应力结构系统是保障结构正常工作的屏障,为了对预应力系统的有效性作出可行性评估,在整个预应力系统中选取了两根水平环向束作为原位检测束。现场采用VH10000型振弦式测力计进行检测,通过试验实测数据和理论计算相互比较,确定安全壳是否能够投入使用。

| Abstract: | Prestressed system is an important safeguard of containment structure.For the evaluation of time dependent losses,two circumferential-horizontal tendons were selected as monitored tendons in situ.In the field experiment VH10000 load cells were introduced.In this paper the differences between practical prestress and theoretical one will be discussed,and finally the conformity between them will be concluded. |

| Keywords: | prestress time dependent losses in-situ-monitoring load cell containment structure |
