单跨大跨度现浇刚构人行桥舒适度分析

刚构桥是桥梁设计中较为成熟、应用比较广泛的桥型，但一般情况下，大跨度刚构桥以车行桥为主，很少对人行工况下的舒适度进行验算。目前在城市建设中的大跨度人行桥大多采用钢结构或组合结构桥梁，但是在一些特殊的情况下，现浇结构有其不可替代的优势。以单跨50 m刚构桥为例，介绍了单跨大跨度现浇刚构人行桥的舒适度验算方法，为类似工程提供经验参考。

Analysis on Comfort Level of Single-span Long-span Cast-in-situ Rigid-frame Pedestrian Bridge

rigid frame bridge is a mature and widely used bridge type in bridge design, but generally, long-span rigid frame bridge is mainly vehicle bridge, and the comfort under pedestrian conditions is rarely checked. At present, steel structure or composite structure bridge is mostly used for long-span pedestrian bridge in urban construction, but in some special cases, cast-in-situ structure has its irreplaceable advantages. This paper takes single span 50m rigid frame bridge as an example, This paper introduces the comfort checking calculation method of single span and long-span cast-in-situ rigid frame pedestrian bridge, which provides experience reference for similar projects.
