The Control Of Construction Of Large-sized Cable-stay Bridge

It is more important that course control in the construction of large-span cable-stay bridge,so the emulation of bridge construction take a key role. Since the means during the formulation of cable-stay bridge often use the suspend means and the suspend span is getting more and more long,at the same time the strength of cable will been change multi times . so to get the more precisely emulation of construction of bridge get an importance in safe and precision of construction.The theme get the integration between design of the large highway bridge in Anqing and theory studying,carry out an research in emulating calculation of steel box beam cable-stay bridge. The theme used the transfer-matrix in solving computing of cable-stay bridge structure,got a improving in computing of cable and the load and landed of cable strength. In order to get an better control in horizontal displacement of tower top and the internal strength and displacement in beam,the theme take an circulating forth piece together means and get to a good target. The theme carry the theory through BSAP program in design of the large highway bridge in Anqing and prove the theory of the theme's useful and availability.
