摘　　要：铁路站房屋面常采用跨度大、面积大、质量大的钢网架结构,且内部空间复杂多样,给工程施工带来很大挑战。以郑阜铁路许昌北站为依托,采用分阶段整体顶升法解决了钢网架整体顶升稳定性、同步误差、纠偏控制及中间层阻碍等问题,保证了钢结构的安装精度,缩短了工期,有效提高了工程质量,减小了高空作业风险,可为类似工程提供参考借鉴。Railway station buildings are often made of large-span, large-area and large-mass steel trusses with complex and diverse internal space, bringing great challenges to engineering construction. This paper, by taking Xuchang North Railway Station of Zhengzhou-Fuyang High Speed Railway as an example, looks at the staged integral jacking method which solves the problems of integral jacking stability, synchronization error, deviation rectification control, and intermediate layer obstruction for steel trusses, thus ensuring the installation accuracy of the steel structure, shortening the construction period, effectively improving the project quality, and reducing the risk of operations at height. The study results can be provided as a reference for similar projects.
