双S曲线连续梁桥复杂后张法预应力施工技术

The construction technology of the continuous beam bridge the post-tensioning method prestressed of the double S complex linear

根据店集一号立交桥的施工特点,对后张法双"S"复杂张拉线形进行了总结,从科学和实践经验双重角度出发,采用先进的工艺、技术和合理的过程,使双"S"复杂曲线预应力张拉达到预期效果,为其他工程提供了经验参考。

According to the construction characteristic of Dianji No. 1 overpass, the paper summarizes the double ＂S＂ complex linear in the course of the post-tensioning method, the data computation and so on. Basing on the science and the praCtical construction experience, we took the advanced crafts, technique and reasonable process, and the double ＂S＂ complex linear pulling of the steel wire has achieved the expected result, which will provide a better reference for the other construction.
