摘要
结合四角田特大桥的施工实践,介绍了T构桥施工中纵向预应力施工的工艺和质量要求及在预应力施工中出现以及可能出现的各种影响预应力质量的原因和因素,并对其进行分析,提出了如何处理这些问题的方法,可为同类工程提供参考。
Combined with the construction of Sijiaotian Grand bridge, the process and quality requirements of vertical prestressing construction of T-frame bridge, and the factors appearing in the prestressing, which can impact on the quality of prestressing construction, were introduced and analyzed. Some measures were put for-ward to deal with these problems, which could provide reference for similar projects.
