钢混组合梁桥桥面连续后浇段施工技术分析研究

Analysis and Research on Construction Technology of Continuous Post Pouring Section of Steel Concrete Composite Beam Bridge Deck

桥面连续是简支梁桥有效连接成整体的关键工序,对提高行车连续性、舒适性、平稳安全等要求起着关键作用。针对钢混梁桥桥面板的结构受力特性,防止出现病害裂缝反射到路面结构层。结合后浇段施工现场生产过程实际情况,重点阐述施工过程、分析受力等因素,总结施工方案进一步在桥梁施工中推广应用。

Deck continuity is the key process of simply supported beam bridge effectively connecting into a whole,which plays a key role in improving the driving continuity,comfort,stability and safety.According to the structural mechanical characteristics of steel-concrete beam bridge deck,the disease cracks are prevented from reflecting to the pavement structure layer.Therefore,how to solve the disease of continuous post cast section of bridge deck has become a hot topic in bridge construction discussion.Therefbre,combined with the actual situation of production process of post cast section construction site,focuses on the construction process,analyzes the force and other factors,summarizes the construction scheme,and further promotes the application in bridge construction.
