摘　　要：针对钢结构连廊高空安装施工工艺,总结了目前常用的几种方法,分析了其优缺点。为进一步探究超大型钢桁架连廊高空安装方法,以济南市某区的产业园项目超大型钢桁架连廊为研究对象,从桁架组装及提升原理出发,结合工程实际,剖析施工难点与相应的解决方案,通过有限元分析,定量分析桁架提升过程中的最不利受力状态。结果表明,采用液压整体提升技术进行高空安装可有效提高桁架的安装效率及施工安全性,针对缺乏支撑条件的超大型钢连廊,采取临时支撑体系可实现整体安装,该结果对于此类施工项目具有较大的技术参考价值。According to the construction technology of high-altitude installation of steel truss corridor,several commonly used high-altitude installation methods are summarized,and their advantages and disadvantages are analyzed.In order to further explore the high-altitude installation method of ultra-large steel truss corridor,taking the ultra-large steel truss corridor of an industrial park project in a district of Jinan City as the research object,the main construction difficulties and corresponding solutions are analyzed from the principle of truss assembly and lifting,and combined with the engineering practice.And finally the most unfavorable stress state in the lifting process of the truss is quantitatively analyzed through finite element analysis.The results show that the hydraulic integral lifting technology can improve the installation efficiency and construction safety of the truss.For oversized steel corridors that lack supporting conditions,an innovative temporary support system can be adopted to achieve overall installation.For such construction projects,it has great technical reference value.
