摘要
重庆菜园坝长江大桥主桥采用Y形刚构与钢箱系杆拱、钢桁梁组合结构,系杆拱主跨420 m。介绍有大悬臂、不对称三维空间特点的Y形刚构支架法施工技术。
The main bridge of Caiyuanba Changjiang River Bridge in Chongqing is designed as a hybrid structure composed of Y-shape rigid frame, steel box bowstring arch and steel truss girder with the main span of the bowstring arch 420 m. In this paper, the construction techniques of scaffolding method for the Y-shape rigid frame structure characterized by long cantilevers and asymmetric three-dimensional space are dealt with.
