摘要
重庆菜园坝长江大桥主桥Y形刚构上部结构为空间扭转结构,纵、横向均有较大倾角,现浇节段重量大,施工临时支架高,施工难度大。介绍Y形刚构现浇移动模板体系结构设计。
The superstructure of the Y-shape rigid-frame structure of the main bridge of Caiyuanba Changjiang River Bridge in Chongqing is a spatially torsional structure with fairly great inclination angles in both longitudinal and lateral directions, and the superstructure is also characterized by heavy weight of each cast-in-situ segment, high temporary construction scaffolding and considerable difficulties of construction. In this paper, the design of the slide shuttering system for cast-in-situ construction of the superstructure of the Y-shape rigid-frame structure is presented.
