摘要
针对武汉大学大学生体育活动中心大跨度X形张弦桁架结构顶推施工控制,从顶推支撑体系的设计与布置、顶推主动控制目标确定、精确可调的同步顶推装置设计、顶推工艺流程以及顶推过程中的数据监控等方面详细阐述了顶推主动控制技术,该结构顶推施工实现了平稳、安全、可控。
In this paper,according to the construction control of the large-span X-shaped string truss structure of the Wuhan University Sports Center,the active control technology of the roof is put forward in detail,from the design and arrangement of the top support system,the active control target of the top push,the precise and adjustable jacking device design,and the data control in the process of pushing up and so on,which realizes the smooth,safe and controllable construction.
