RESEARCH ON CONSTRUCTION CONTROL TECHNOLOGY OF STEEL-CONCRETE COMPOSITE BEAMS FOR LONG SPAN TWIN TOWERS IN BRIDGE ENGINEERING
Taking the double-tower steel-concrete composite beam structure of a long-span bridge project in a certain area as an example,combining with the actual situation of the project,the construction control difficulties of the project are analyzed,and the construction control principles are determined,and the linear control of the main tower,the stress control of the main beam,the cable force control,and the closing control of the steel box beam are carried out.After testing the control effect,it is concluded that the maximum control error of beam top elevation is 15.6 mm,and the control deviation of cable force is less than 5%,which meets the construction standard of bridge engineering.
