摘　　要：网架结构具有空间刚度大、整体性好、抗震能力强等优势,因此,被广泛应用于房屋建筑工程中,但网架结构的复杂多样给建筑施工带来了巨大的挑战。论文以费县通用机场机库为具体工程案例,对基于液压千斤顶的2种整体顶升方法:上端式整体顶升和下端式整体顶升进行对比分析。实践表明,相比上端式整体顶升,在满足验收要求的前提下,下端式整体顶升方法不但可以减少高处作业风险,而且可以缩短工期,大大提高了工程施工效率。Grid structure has the advantages of large spatial stiffness, good integrity and strong seismic capacity, so it is widely used in housing construction engineering. However, the complexity and diversity of grid structure brings great challenges to building construction.Taking the hangar of Feixian County general airport as a specific project, this paper compares and analyzes the two integral jacking methods based on hydraulic jack, the upper end integral jacking and the lower end integral jacking. The practice shows that compared with the upper end integral jacking, on the premise of meeting the acceptance requirements, the lower end integral jacking method can not only reduce the risk of high-altitude operation, but also shorten the construction period, The construction efficiency of the project is greatly improved.
