武汉火车站三跨连续刚构拱桥模板体系设计

Formwork System Design of Three-span Continuous Rigid Arch Bridge in Wuhan Station

武汉火车站是国内第一个采用桥建合一的高速铁路客运专线火车站。站房由10座高架桥平行布置组成。其中三跨连续刚构拱桥为单箱五室箱形截面,桥面呈槽形,底部为鱼腹式。混凝土外观质量要求为清水饰面混凝土。结合桥梁施工方案进行模板及其支撑体系的研究,提出安全、可靠、高效的模板体系设计方案。

Wuhan Station is the first high-speed railway passenger line station which combines bridge and building function in China. The station building consists of ten parallel viaducts,in which three-span continuous rigid arch bridge,with single-box five-chamber box section,channel deck and fish-bellied bridge bottom,is as-cast concrete surface. Combining with bridge construction schemes,the authors study formwork and scaffolding system,and put forward safe,reliable and high efficient design scheme of formwork system.
