路基改桥梁施工在互通立交改造工程中的应用

Application of Subgrade to Bridge Construction in Interchange Reconstruction Project

文章介绍了京港澳高速互通立交将部分施工路段原有路基工程改造成JGAK2+683.142桥梁的施工工法,目的是解决新建双湖大道市政道路与既有京港澳高速道路交叉通行的问题。通过对既有路基改桥梁工程施工技术的探索,证实了在该工程中,路基改桥梁施工的应用具有可行性。

By introducing the construction method of transforming the original subgrade project into JGAK2+683.142 bridge for some construction sections of the Beijing-Hongkong-Macao expressway interchange,this paper effectively solves the problem of cross-passage between the new municipal road of Shuanghu avenue and the existing Beijing-Hongkong-Macao expressway,and explores the construction technology of the existing subgrade bridge project.It is feasible to get a way out of the foundation and change the bridge construction.
