Abstract
Take Sutong Bridge as the subject investigated, the correctness of the geometry control theory is verified by the numerical simulation analysis. The influences of structural geometric shape induced by temporary loads and temperature field during the construction procedure are investigated. Taking the impact of geometry non-linear during construction into account, the simulation results indicate that only the stage state of the structure during construction is affected and the completion stage state is not affected. Geometry control theory applied to control the super-span cable-stayed bridge construction, and satisfied outcome of construction control can be achieved based on geometry control theory.
