[摘要]大唐洛阳热电公司干煤棚采用了大跨度预应力钢桁架结构,鉴于施工现场堆煤区无法移走的条件限制,该工程采用了累积滑移加分段吊装的施工方案,其中预应力的施工贯穿于整个施工过程中。施工前进行了施工模拟仿真计算分析,确定了施工方案,指出了施工技术重点及预应力张拉施工要点。同时,在施工中进行了施工监测,监测结果证明,施工成果完全达到要求。

Abstract: The long span prestressed steel truss structure is adopted in the dry coal shed of Datang Luoyang Thermal Power Company. In view of the limitation that the coal piling area on the construction site cannot be removed, the project adopts the construction scheme of accumulative sliding and segmental hoisting, in which the construction of prestress runs through the whole construction process.The construction simulation calculation and analysis were carried out before the construction, then the construction scheme was determined. The construction monitoring was carried out during the construction, and good construction results were obtained. The construction technology and construction method of this kind of structure can provide reference for similar projects.

Keywords:steel structures; cables; prestress; sliding; construction
