摘要
在介绍南京长江第四大桥短线匹配节段箱梁预制和安装施工的基础上,对施工现场的关键工序和技术做了进一步的研究和探讨,主要包括预制过程中模板系统的控制、预制和安装过程中的线形控制以及安装过程中预应力的施工控制等几个方面.
Based on the introduction of the prefabrication and the installation of the short-line matching segmental box girder on the fourth bridge over the Yangtze River in Nanjing, this thesis makes a further study of the critical construction procedures and technologies including several aspects such as the control of the formwork system in the process of prefabrication, the linear control of the prefabrication and installation procedure, and also the construction control of the pre-stressing force in the process of installation.
