Description
Technical field
The present invention relates to technical field of bridge engineering, specifically a kind of semi-rigid sling arch bridge and its construction method.
Background technique
Suspended ribbon bridge is assembled on the linear rope of stretched wire by very thin concrete bridge deck board member.The spy of this bridge
Point is its continuous complementary smooth curve, and internal force transmitting is clear, and the material that this bridge structure uses is considerably less.Application number
A kind of concrete self-anchored type suspended ribbon bridge of smooth arch rib of bridge floor band, the sling are disclosed for the Chinese patent of CN201510454255.X
Smooth arch rib is set on the bridge floor of bridge and is connect with tie-rod with bridge floor and column, by adding convex smooth arch rib, makes self-anchored type bridge
The neutral conductor of face structural section rises, and improves bridge deck structure height of C.G., and share a part of bridge dead load, to reduce outstanding
With bridge lower edge to the axis compression of floorings, but the Abutment of this suspended ribbon bridge needs to bear very big horizontal thrust, causes
The difficulty of construction of abutment is larger, costly, and safety is lower.Based on this point, propose arch and sling combining shape
At the new system from anchor structure.
There are two types of forms for the combination of sling structure and arch structure at present, and one is slings to be supported or suspended from arch, another
Kind is curved suspended ribbon bridge peace arch structure.Both structure type sling structures are by arch brace or are suspended on arch, and structure forms one
A self-anchoring system.But existing sling arch bridge does not have support or expansion joint, using welding and bolt between sling structure and arch structure
It the rigid connection such as connects, limits the relative displacement of two kinds of structural system junctions, lead to rigidity between sling structure and arch structure
Differ larger, relative displacement is small and energy dissipation capacity is poor, to reduce the overall stability of sling arch bridge.
Summary of the invention
In order to solve the above problem present in the prior art, the present invention provides a kind of semi-rigid sling arch bridges, and change
Into its construction method, floorings, abutment and support frame varied rigid link can be made, can effectively solve sling structure and arch structure it
