摘要
针对山区高墩大跨度连续刚构桥梁施工的特点,结合工程实例,从主梁结构设计、悬臂浇筑施工技术要点、高墩边孔现浇施工、合龙段施工与体系转换控制技术等方面,对连续刚构桥梁施工技术难点和重要控制环节进行系统地分析,可为类似工程项目提供参考和借鉴。
In the light of construction features of high-pier large span continuous steel bridge in the mountainous area,combined with engineering practice,the construction technology difficulties and important control points of continuous steel bridge are analyzed from aspects of structure design of main girder,construction techniques of cantilever casting construction,cast-in-place construction of furnace hole,construction and system transformation controlling technology of closure segments.It can provide reference for related engineering projects.
