This paper takes integral elevation construction of the steel truss roof structure of a hangar as the example to mainly introduce the technological principle of the synchronous overall elevation technique of the grid structure, arraignment plan design and the main construction process of the elevation. At the same time, the finite element analysis software MIDAS/Gen V8.2.0 is used to carry out the simulation analysis to ensure the quality and safety of the elevation engineering.%以某机库钢网架屋盖整体提升工程为例,重点介绍了网架结构同步整体提升技术的技术原理、提审方案设计、提升的重点施工工艺,同时应用有限元分析软件程序MIDAS/Gen V8.2.0仿真分析,以确保提升工程的质量和安全.
