试论桥梁建筑中预应力施工技术

On prestressed construction technique in bridge buildings

通过对桥梁工程建设现状的研究,介绍了孔道、下料、穿筋、张拉及封锚等桥梁预应力技术的施工内容,并对梁体预应力施工要点和应注意事项进行了阐述,指出在桥梁结构中应用预应力技术,提高了桥梁结构的张拉性能,保证了桥梁结构的稳定性。

According to the studies on the construction of bridge projects, the paper introduces the construction contents of the bridge prestressed technique, including the pore canal, the material preparation, the reinforcement, the tension, and the sealing anchor, illustrates the beam pres- tressed construction points and precautions, and points out the prestressed technique can be adopted in the bridge structure, so as to improve the tension performance of the bridge structure and ensure the stability of the bridge structure.
