Cable-stayed Bridge Ideal Bridge State And The State Of Reasonable Construction

In this paper through analyzing and summarizing to the research achievement and project practise in ascertaining ideal finished state and rational construction state of analyzing cable-stayed bridge at present, there are not a series of systemic theory and method in actual application. Many studies have been carried out in the aspect of designing and calculating of cable-stayed bridge based on Xian Tao han Jiang highway bridge. The optimization model of the cable tensile force is established, resolving the ideal finished state of considering syntheticly the requirement including the dead load ,active load and presress of structure, meanwhile, providing a forward-calculating method for determining the rational construction state on the foundation of the optimization model .On the other hand how to determine and adjust the important parameter, the cable midst tensile forces and the main feam form setting levels in constructing cable-stayed bridge, has also been analyzed, besides, the corresponding calculation method is introduced and applied to the actual construction controlling of Xian Tao han Jiang highway bridge well.
