摘要
预应力混凝土连续梁桥采用挂篮现浇悬臂施工,施工技术要求高,为使得该桥顺利合拢,符合设计要求,对该桥进行施工控制。通过现场施工控制,该桥中跨合拢时的合拢段两端实测高程差与施工控制预计高程差在监控要求的范围内,应力也在设计要求的范围内,说明该桥的施工控制是成功的,从而为工程施工提供一种有效施工控制技术。
The continuous prestressed beam was constructed with cantilever construction, this construction was high of technology, so the bridge was supervised and controlled in the whole construction. The high- ness difference of theory and practice is accord with the code, the cantilever construction of the continuous box girder is succeeded in construction control. This refers to the construction of this sort bridges.
