谈大跨度预应力混凝土桥梁施工控制技术

Experience summary of construction control technology for long span prestressed concrete bridge

主要探究了桥梁架构参数、温度、建设所用材料、构架分析模型等对大跨度预应力混凝土技术的影响,并以此为基础,分析了针对桥梁主体构架的变形控制、针对桥梁主体构架的应力控制等控制因素,最后探索出了构架分析技术及构架分析技术在桥梁建设工程中的应用,对进一步提升桥梁工程项目的建设质量起到了一定的借鉴作用。

This paper explores the bridge architecture parameters,temperature,construction materials,structure analysis model of long-span prestressed concrete technology,and on this basis,analysis of the deformation control for the main bridge structure for main bridge structure stress control factors,finally explores the framework analysis and application and the frame analysis technology in the construction of bridge engineering in our country,the reference to the construction of our country to further improve the quality of bridge engineering project.
