摘要
大跨度空间结构施工干扰因素多,容易产生较大的附加内力和变形。系统研究施工方法及相应关键性技术问题,可以帮助施工技术人员深入了解施工过程中内力及位移变化情况,从而彻底排除施工安全隐患,有效减少安全事故的发生。文章对超大跨度预应力钢拱桁架施工技术进行了探究,以供参考。
System research and construction methods and corresponding key technical problems can help construction technicians to deeply understand the internal force and displacement changes during the construction process,thus completely eliminating construction safety hazards and effectively reducing the occurrence of safety accidents.
