Abstract

Research purposes:A single tower four spacial cable faces prestressed concrete cable-stayed bridge is adopted on the main road crossing the existing major railway in one city,the construction used rotating methods,rotating weight was 33,000 tons,far beyond the existing engineering practice,to provide the basis for the research of suitable rotating hinge type of large tonnage rotating construction in the engineering.
Research conclusions:(1)The stiffness of sphere hinge is greater than flat hinge,the ability of sphere hinge adapting to the eccentric load is stronger than flat hinge.(2)The forces of concrete at the bottom of the sphere hinge are less than flat hinge.(3)At rotating support coordination,rotating structure stress and deformation uniformity,stability of traction,rotating safety,beam body attitude adjustment after rotating,construction of implement,adjustable performance when problems and so on,the sphere hinge all have better performance;the flat hinge requirements of construction control is much higher, the load asymmetric distribution from upper rotating structure and the mounting surface error will affect the rotating reliability significantly.(4)The selected type of sphere hinge in the rotating design of super large tonnage of 33,000 tons is appropriate.(5)The study may provide a reference for super large tonnage rotating construction crossing the existing structure with large span bridge,and strongly expand the scope of application of rotating construction method.
