Simulation analysis is the basis for construction control of cable-stayed bridges, it monitors the process of the bridge construction. The relationship and importance of simulation and construction control are introduced in the paper. Based on the finite element theory and combined with construction theory of the cable -stayed bridges, according to use the software Midas/Civil, the construction characteristics of Masangxi Bridge is researched by making use of the forward calculation method and the backward calculation method. The results show that the system transformation of the bridge is occurred during the construction, thus, it is important to carry out careful and detailed forward simulation to ensure the safety of construction structure and meet with design requirements. The reasonable results can be drawn when the backward calculation method is combined with the forward calculation method.

In order to improve the construction control precision of long-span hybrid girder cable-stayed bridge, the design parameters such as the weight of girder, the cable tensile force and the stiffness of cable are conducted sensitivity analysis through computing and comparing the influences of these parameters on the deflection of girders, the stress of girders and the cable force in the bridge's completion state. It was shown by the computation results that the main parameters of long-span hybrid girder cable-stayed bridge are the weight of girder and the cable tensile force, the stiffness of cable has a little influence on the completion state of the bridge. With this approach, through modifying the main parameters, while ignoring the influences of the secondary ones, the Jingyue Yangtze River Highway Bridge construction control has been successfully done. The test results show that the cable force and the contour of the bridge are in good state. They are both in the range of control, the relative error of the cable force is less than 3% and the elevation deviation is less than 5mm.
