大跨径连续桥梁施工工艺研究

Research on Construction Technology of the Large-span Continuous Bridge

大跨径连续梁桥属于常见的桥型,跨径较大,施工要求高。鉴于此,文章结合大跨径桥梁工程实例,介绍连续梁桥支座安装、模板制作与安装要点,并就钢筋工程、混凝土工程及预应力工程施工技术措施展开详细的研究。在科学规划和规范施工下,案例工程施工单位高效完成了大跨径连续桥梁的各项建设工作,施工全程安全状况良好,施工质量可靠,工程采用的大跨径连续桥梁施工工艺具有可行性。

The large-span continuous beam bridge is a common bridge type with large span and high construction requirement.In view of this,combined with the example of large-span bridge engineering,this paper introduces the key points of support installation,formwork production and installation of the continuous beam bridge,and studies the technical measures of steel bar engineering,concrete engineering and prestressed engineering construction in detail.Under the scientific planning and standardized construction,the construction unit of the case project efficiently completed the construction work of the large-span continuous bridge.The safety condition throughout the whole construction process is good,the construction quality is reliable,and the construction technology of the large-span continuous bridge used in the project is feasible.
