滑移施工技术在超大跨度拱形管桁架中的应用

Application of Sliding Construction Technology in Super Large Span Arch Pipe Truss

以某电厂煤场封闭改造工程为例,介绍超大跨度拱形管桁架结构工程特点及难点,系统阐述滑移施工总体方案、施工步骤及施工验算。采用有限元软件对滑移施工过程进行仿真模拟计算,并对主要施工阶段计算结果进行分析,确保了施工安全。

Taking the coal yard closed reconstruction project of a power plant as an example,the characteristics and difficulties of super large span arch pipe truss structure engineering are introduced,and the overall scheme,specific construction steps and construction checking calculation of sliding construction are systematically expounded.The finite element software is used to simulate the sliding construction process,and the calculation results of the main construction stages are analyzed to ensure the safety and reliability of the construction.
