| Abstract: | The scheme design of combination bracket for 3spans cast-in-situ prestressed continuous box beam of Qianhe super-large bridge adopts the combination structure of upper bowl-buckle falsework and lower bracket of bailey truss beam. Checking results of combined bracket＇s strength,stiffness and stability shows that bracket mechanical properties conform to the specification requirement,which provides references for similar bracket scheme design of temporary structure in future. |
