预制安装的施工工艺是当今主流建设工艺,以工期较短,生产构件通用,施工较为简易而被广泛应用到各个建设项目中。在桥梁建设中,节段预制拼装施工方法自从上世纪60年代法国成功建设后也逐渐在各国流行开来,发展到现在,桥梁建设中节段预制拼装工艺已经逐渐成熟且结构更加清晰。本文系统的分析了节段预制施工工艺的预制类别,施工工艺的类型和技术重点,以及当前控制桥梁预制施工线型的主要办法和重点。为以后技术的深入研究提供参考。
Prefabricated installation of the construction process is the current mainstream construction technology, with a shorter duration, common production components, construction is relatively simple and has been widely applied to various construction projects. In the bridge construction, the segmental prefabricated assembly construction method has gradually become popular in all countries since the successful construction of France in the 1960s. Nowadays, the prefabricated assembly process of the bridge construction has gradually matured and the structure is clearer. This paper systematically analyzes the types of prefabricated prefabricated construction technology, the type of construction technology and technical focus, as well as the current main methods and key points to control the prefabricated construction of the bridge. For future technical in-depth study provide a reference.
