现浇预应力箱梁预拱及起拱分析与探究

The analysis and research on pre-arch and arch camber of cast-in-situ pre-stressed box girder

对现浇预应力箱梁的预拱及起拱问题进行了分析,并结合以往成功案例,对设计质量好的预应力箱梁进行观察和研究,通过对预拱和起拱部位进行优化分析和改良,以确保后期施工的建筑尺寸和质量满足现代标准的要求。

This paper analyzed the pre-arch and arch camber problems of cast-in-place pre-stressed box girder, and combining with the previous successful cases, observed and researched the pre-stressed concrete box girder with better design quality, through the optimization analysis and improvement on pre-arch and arch camber part, so as to ensure that the building size and quality of post construction to meet modem standards.
