THE CONTROL TECHNIQUE OF NACHAOKOU BRIDGE IN XIAMEN OF CHINA

摘要：

In this paper, the key technologies of construction control of X-type steel box tied arch bridge constructed by full framing are discussed in detail with the Nachaokou Bridge in Xiamen City in China as engineering background. Firstly, simulation the interaction of pile foundation、 tie-bar and arch rib in construction process .Secondly, effect of longitudinal gradient is taken into account in simulation calculation of tensioning force of the tie members. Thirdly, the effects of braces deformation and temperature change on assembling location of arch rib were put on much emphasis. Finally, Pre-jacking transverse brace and optimizing procedure of tensioning tie bar is discussed.
