| Abstract: | During the construction of Chaotianmen Yangtze River Bridge, a hoisting cantilever crane machine on the truss arch was used, assisted by a major cable-stayed system in the process. By using a space finite element model, analysis of the construction of Chaotianmen Yangtze River Bridge was accomplished. From three perspective： the theoretical analysis,the measured data and the construction operation, a comprehensive analysis of initial tension was carried on. Also the analysis of these measured data was given. |
