Jacking Construction Technology of Long Span Continuous Frame Bridge Under Railway Existing Line
Taking Xianghe Road as an example,this paper probes into the application of jacking con-struction technology of long-span continuous frame bridge under railway existing line.On the basis of the ex-cavation of the pit and the construction of prestressed anchor cable,the stability of the foundation pit is im-proved,which creates favorable conditions for the construction of framed bridge.In order to save the con-struction period,the prefabricated frame bridge is used in this project,and the hydraulic system is used to carry out the jacking after the quality is checked and qualified.During the jacking,the observation and devi-ation control are made,and the jacking task of the frame bridge is successfully completed.
