| 摘 要： | 该文以体外预应力在某连续梁桥加固中的应用为例,介绍体外预应力在连续箱梁中的布置形式、锚固方法和转向块设置等。加固后桥梁的动静载试验,以及后期的运营状态观测表明采用体外预应力加固后,原结构的应力状态和强度得到了改善,为今后桥梁加固提供了一种新的思路和解决方法。

| Abstract: | The article describes the application of external pre-stressing in the reinforcement of a continuous girder bridge, introduces the arrangement type, anchorage method and turning block setup of the external pre-stressing in the continuous box girder. The dynamic and static loading tests of the reinforced bridge and the observation of its post-operation status show that the stress state and strength of the original structure are improved after the external pre=stressing reinforcement, which provides a new thought and solving method for the bridge reinforcement in the future. |
