摘　　要：钢结构桥梁顶推施工过程中,对主桥各个构件进行应力监控显得非常重要。在桥梁工程顶推施工过程中,导梁是一个非常重要的辅助结构。应用了顶推法的施工原理和施工方法。以实际工程为例,对模拟顶推过程进行分析,探讨钢结构桥梁大跨度顶推施工技术,介绍顶推施工法的工作原理,具体研究钢结构桥梁超重柔性钢梁大跨度顶推施工的施工工艺、施工准备、技术要点和施工过程控制要点。In the process of steel structure bridge jacking construction, it is very important to monitor the stress of each component of the main bridge. Guide beam is a very important auxiliary structure in bridge jacking construction. The construction principle and method of pushing method are applied. In practical engineering, for example, to analyze simulation pusher, explore, large span steel bridge jacking construction technology, this study introduces the working principle of jacking construction method, concrete research of steel bridge overweight flexible large span girder construction technology of jacking construction technology, construction preparation, main technical points and construction process control points.
