摘　　要：随着既有铁路改建规模的扩大和地方涉铁工程项目数量的逐年增加,既有铁路施工安全问题愈发重要,施工标准和要求越来越高。以邳州市建设路下穿铁路立交工程中邳州站13道T梁在铁路接触网软横跨不迁改的情况下原位拆除工程为例,简单介绍满堂支架+折臂吊组合法代替常规汽车吊整体抬吊法。With the expansion of the scale of existing railway reconstruction and the year-on-year increasing in the number of local railway-related projects, the safety issue of existing railway construction is becoming more and more important and the construction standards and requirements are becoming higher and higher. The paper briefly introduces the combination method of full support + folding arm crane instead of conventional car crane lifting method in the case of in-situ demolition of 13 T-beams at Pizhou station without the railway contact network in the construction project of Pizhou Jianshe Road under-passing railway interchange.
