General Design and Technological Innovation of Self-anchored Suspension Bridge for New Taiping Bridge in Shang-hai Pudong
The main bridge of the new Taiping Bridge is a double-span continuous asymmetric single-pylon self-anchored suspension bridge.Its span layout is 112 m+72 m=184 m.The overview,aesthetic design concept,overall layout and structural design,project characteristics,technical difficulties,and solutions of the New Taiping Bridge Project are briefly introduced.The equal beam height design of main cable anchorage zone is used for this bridge.The anchorage structure is simplified.A series of new materials,new processes and new technologies are used to lengthen the durability of this bridge and reduce the maintenance workload and cost.The prestressed base slab is used to solve the collinearity problem of subway shield.The design scheme can provide the reference for the design of similar bridges.
