摘　　要：国家智能电网研究院建设工程办公科研楼共存在5处钢连廊,均为空间钢桁架结构,具有跨度大、质量大、悬空高度大等特点,结合现场实际情况,采用计算机控制液压千斤顶整体提升这一先进施工技术将各钢连廊依次吊装就位。介绍了整体提升的重点施工工艺,同时应用有限元分析软件Midas对提升施工工况进行计算分析,确保提升工程的质量和安全。There are five steel corridors in office and research building of State Grid Institutes Construction project. All the five corridors are spacial steel truss structure with large span, heavy weight and large hanging height. Based on site conditions, the steel corridors are integral lifted and positioned with hydraulic jacks under the control fo computers. The key technology of integral lifting is emphasized. The quality and safety of the lifting can be realized through calculation construction conditions with the software Midas.
