摘要
以广湛高铁广珠广茂联络线上行线特大桥96 m钢桁梁采用拖拉法架设施工为实例,阐述拖拉施工中临时支墩的设计和验算,拖拉的关键步骤、落梁及纵横向纠偏等关键技术,并对拖拉过程中结构的安全和整体稳定进行了验算,为同类工程积累了经验。
Taking the drag-pull erecting construction method applied in extra-large bridge 96 m steel truss beam on the upstream line of Guangzhou-Zhuhai-Guangmao liaison line of the Guangzhou-Zhanjiang high-speed railway as an example,the thesis illustrates the the temporary pier design and checking in drag-pull construction process,critical drag-pull procedures,falling beam and vertical-horizontal correction and other key technologies,and carries out checking calculation on the structural safety and integral stability in drag-pull construction process,which has accumulated experience for similar engineering.
