下穿既有道路现浇框架桥施工技术研究

Study on Beneath Situ Frame Bridge Construction Technology

结合成昆线读书铺车站框架桥工程,对某工程下穿既有道路现浇框架桥工程的线路加固处理、线路架空处理、框架桥现浇及线路恢复施工的施工方案及工艺进行了阐述,可为后续同类工程施工提供参考依据。

Chengdu-Kunming line shop stop reading frame bridge project, through the existing line cast frame bridge project under the reinforcement line, the line overhead processing, and cast frame bridge circuit recovery construction program and construction process were forth, can provide a reference for future similar projects.
