                                  [摘要]大唐洛陽熱電公司干煤棚采用了大跨度預應力鋼桁架結構,鑒于施工現場堆煤區無法移走的條件限制,該工程采用了累積滑移加分段吊裝的施工方案,其中預應力的施工貫穿于整個施工過程中。施工前進行了施工模擬仿真計算分析,確定了施工方案,指出了施工技術重點及預應力張拉施工要點。同時,在施工中進行了施工監測,監測結果證明,施工成果完全達到要求。

                                  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.
