拆除既有铁路桥梁并顶进框架桥关键技术

Critical technology of dismantling existing railway bridge combining with jacking frame bridge

结合潍坊市潍州路工程实例,详细介绍了框架桥顶进施工方案,从线路加固设计、拆除既有线下桥梁施工设计两方面入手,阐述了具体的工艺流程及采用的关键技术,为解决类似问题提供了较好的解决方法。

Combining with Weizhou railway engineering example in Weifang city,the paper specifically introduces frame bridge jacking scheme. Starting from two aspects of route reinforcement design and dismantling existing underground bridge construction design,it describes technological procedures and critical technologies,which has provided better solutions for similar problems.
