RESEARCH ON THE APPLICATION OF INTEGRAL HOISTING TECHNOLOGY FOR LARGE-SPAN STEEL-CONCRETE COMPOSITE BEAMS CROSSING RIVER CHANNELS
With the continuous development of bridge structural forms,steel-concrete composite beams,as a new type of bridge structure,have begun to be widely used in China.Due to its lightweight,high flexural stiffness,and small cross-sectional size,the steel-concrete composite beam structure can effectively reduce the requirements for bridge foundations.The steel-concrete composite beam has the advantages of reducing the use of steel,lowering engineering costs,and having lower construction difficulties in highway construction,so its application will become increasingly widespread.This study takes the Shanghai Tong Railway Yangtze River Bridge as an example to introduce a construction technology for the overall hoisting of large-span steel-concrete composite beams across river channels,and elaborates on its construction technology and characteristics.
