Design of Main Cable Anchoring and Manufacturing of Cast Steel Anchor for Self-anchored Suspension Bridges
The main cables anchoring area is a key part of the self-anchored suspension bridge,and its structural type partly determines the overall bridge arrangement.In terms of the difficulties in the design and construction of main cables anchor,four main cable anchoring methods,applicable conditions and relative merits were compared and analyzed.Then an example of the Jiuqiao Road bridge was taken,the overall design,main cable anchoring of steel structure were introduced;the difficulties and key technologies in the manufacturing and installation process of cast steel anchor were explored.The operation after founded show that:1)The overall design,main cable anchoring project are reasonable,channel and road network are adaptively,and the bridge is beautiful;2)Casting and manufacturing technology for cast steel anchor are advanced,anchoring of the main cable is reliably.
