| Abstract: | The Tianjin CiHai Bridge is outlined.The design concept is analyzed,mainly explaining why the hybrid structure of new-style cable-stayed bridge with giant wheel is adopted in the Cihai Bridge.The key points of each specialty,including architecture,structure and road-bridge,are presented.The structural characteristics are studied;and it is found that the loads are mainly transferred by the axial force system.The giant wheel and new-style cable-stayed bridge are analyzed by using the midas software respectively.Main technical problems that need to be solved for the Cihai Bridge are pointed. |
