随着我国城市基础设施建设步伐的逐渐加快,桥梁工程逐渐发展至大跨度的模式,对路桥建设技术形成越来越高的要求。预应力混凝土箱梁存在着结构轻盈、跨径大、经济合理、承载能力强以及施工简单等优势,目前无论是路桥建设,还是高层建筑施工中都得到较为广泛的使用。然而,预应力混凝土箱梁有较多施工环节存在、施工技术要求较高且质量控制难度大,一旦处理不好,则会造成混凝土构件有裂缝问题产生,对桥梁的整体质量造成影响,所以,分析预应力混凝土箱梁施工技术显得极为必要。
With the gradual acceleration of urban infrastructure construction in our country, the bridge project has gradually developed into a large-span model and has become a higher and higher requirement for road and bridge construction technology. Prestressed concrete box girder has the advantages of light weight, large span, economic rationality, strong carrying capacity and simple construction. At present, both the road and bridge construction and high-rise building construction have been widely used. However, the prestressed concrete box girder has many construction steps, which requires high construction technology and difficult quality control. If it is not handled properly, it will cause cracks in the concrete components and affect the overall quality of the bridge. Therefore, Analysis of prestressed concrete box girder construction technology is extremely necessary.
