在市政桥梁施工过程中,跨越既有线路的桥梁上部结构施工通常需要根据被跨道路和新建桥梁的位置关系及被跨线路的通行要求选择适当的施工工艺。通过针对上跨高速道路的桥梁上部结构吊装施工工艺进行探讨,对桥梁拼装施工过程中架桥机拼装、过孔、中边梁架设及施工中安全防护措施等方面进行论述。
In the process of municipal bridge construction, the construction of the superstructure of the bridge across the existing lines usuaIly needs to select the appropriate construction technology according to the position relationship of the cross-roads and the new bridges and the requirements of the cross-line crossing.
