摘　　要：随着城市轨道交通建设的大力发展,越来越多的地下车站也面临着升级和改造。结合上海轨道交通17号线虹桥火车站站改造工程,详细阐述了“托梁换柱”法在运营地下车站改造中的设计思路、方案和要点,运用“施工隔离”、“先撑后拆”、“化整为零”的方法,对“托梁换柱”法的具体实施方案进行了优化。这可为类似地下车站改造提供参考。With the development of urban rail transit construction, more and more underground stations will be upgraded and renovated. The Hongqiao Railway Station Station of Shanghai Rail Transit Line 17 is taken as an example. The design idea, scheme and key points of “underpinning beam and replacing column” in the renovation of underground station in operation are illustrated. And the specific implementation scheme is optimized by the methods of “construction isolation”,“underpinning first and then dismantling” and “breaking up the whole into parts”.
