With Wanzhou Yangtze River Bridge as an engineering example, FEM is applied to simulate the whole bridge construction process to optimize the truss member assembling sequences and determine the critical member bars that should be monitored. Real-time or fixed time data on stress and deflection are collected through a wireless integrated test system. Thus, the status of stress and deflection for the cantilever structure is under good control to ensure safety and stability. Measurements and theoretical computations of temperature effects are valuable for closure time selection and temperature deformation adjustment. The middle span is closed under the conditions of “zero error and zero additional stress”. A successful construction of this bridge provides experience and guidance for other similar bridges.
