泰州大桥钢中塔塔底锚固方式研究

介绍了国内首座三塔悬索桥人字形钢中塔的塔底锚固受力特点,对铰接与固接两种锚固方式进行了分析,对克服塔底水平分力的两种方案进行了深入研究,针对该桥中塔的具体特点,提出了对塔底N、Q、M区分重点、分别予以解决的设计思路和具有特色的锚固方案,为大型钢—混结构锚固方式提供了有益的经验。

Anchorage method research at the middle segmental bottom of the Taizhou Bridge pylons

This paper introduced the behaviors of the middle segmental bottom of the steel pylons of the Taizhou Bridge,which is the first three-pylons suspension bridge,and analysed the methods to control the horizontal force at the segmental bottom with hinge and fixed constraint conditions.According to the characteristics of middle segmental of pylons,the analysis and design methods are suggested that the segments zones at N,Q and M need to be done separately for their unique anchoring programmes,which can provide ...
