Lifting of Steel Pipe Arch Truss Segment of Main Bridge of Wuhan Jianghan No.3 Bridge

The main bridge of Wuhan Jianghan No 3 Bridge is an under\|supporting steel pipe concrete truss non\|hinge tied arch bridge. The lifting of its steel pipe arch truss segment adopted spatial high tower frame structure combined cable tower and anchor tower and mainly controlling the shifting of hanging system combined checking cable force method. With practical projects, authors introduce the construction method and principle, schedule, plan and technical points of the lifting construction of steel pipe arch truss segments.
