Description
Technical field:
The new bridge type of this practicality relates to bridge, relates in particular to a kind of arch composite bridge that tiltedly draws.
Background technology:
In recent years, the Longspan Bridge engineering has had tremendous development, and the suspension bridge span ability is big, in general be suitable for striding greater than the bridge hole of 600m, but the construction of huge anchor ingot of suspension bridge and main push-towing rope, stiff girder all can make the bridge cost increase; Cable stayed bridge then need improve the ratio of deck-molding, tower height and main span and set up measures such as auxiliary pier and improve the rigidity of structure; For arch bridge, the steel arch bridge rolled steel dosage is big, concrete-filled steel tubes arch bridge, and required arch rib section is heavy for balance arch rib thrust, need to adopt bigger tie-rod, and its end bay span ability is limited.
The logical Yangtze Bridge main span of the Soviet Union that China is building reaches 1088m and is the cable stayed bridge of maximum span in the world, king-tower height 308m, suspension cable length 580m; Wushan, the Chongqing Yangtze Bridge main span clear span that has built up is 460m, is the concrete filled steel tube half-through arch bridge of largest span in the world, be seated on the rock of two sides but encircle the angle, and the husky concrete filled steel tube half-through arch bridge of Guangzhou bifurcation hair worn in a bun or coil, main span reaches 360m, and end bay is 76m only.
The bridge architecture of combining form is meant two kinds of different basic bridge architectures is made up rightly, can give full play to the advantage of different bridge architectures, makes structure stress more reasonable, and structure is more stable, thereby can increase the span ability of bridge architecture.Present various combination bridge-type is in the ascendant, but the composite bridge of building both at home and abroad mostly is camber combination bridge architecture, with cable stayed bridge and the two combined bridge construction of arch bridge, had not yet to see the correlative study report, the similar bridge (Putrajaya bridge) that a single hole span 300m is only arranged in Malaysia, Putrajaya bridge suspension cable is directly to be pulled on the bridge floor, and rope, arch are distinguished stressed, are to add an arch bridge on cable stayed bridge.
The utility model content:
The purpose of this utility model is to form a kind of novel arch combination bridge architecture that tiltedly draws for the cable stayed bridge in modern times and classic arch bridge are organically combined, and makes it have good stress performance, reasonably technical-economic index, abundant landscape effect.
For achieving the above object, the utility model bridge type adopts following technical scheme: tiltedly draw the arch composite bridge, comprise main arch rib 1, suspension rod 2, suspension cable 3, bridge tower 4, limit arch 5, end bay girder 6, main span bridge deck 7, main pier 9, it is characterized in that the bridge tower 4 that is positioned at the main span two ends is rigidly connected with main pier 9; The two ends of described main arch rib 1 are rigidly connected with two main piers 9 respectively; Suspension cable 3 two ends in the described main span link to each other with bridge tower 4 and main arch rib 1 respectively, and suspension cable 3 two ends in the end bay link to each other with bridge tower 4 and end bay girder 6 respectively; Described main span bridge deck 7 links to each other with main arch rib 1 by suspension rod 2; 5 upper ends are encircleed on described limit and the end bay girder is rigidly connected, and lower end and main pier 9 are rigidly connected.
Above-mentioned main span bridge deck 7 can by bridge deck and steel in length and breadth beam form suspension system.
Above-mentioned main arch rib can adopt encased structures or empty steel tubular structure or steel case arch structure; Above-mentioned bridge tower can be concrete or steel work bridge tower.
Vertically be provided with tie-rod 8 along bridge floor in above-mentioned main span bridge deck 7 and end bay girder 6, the two ends of this tie-rod 8 are fixed on the end bay girder 6, and pretightning force is arranged.
Therefore suspension cable in the utility model main span, can play interim knotted rope effect owing to directly be pulled on the main arch rib in assembly unit main arch work progress, and in bridge operation stage, it is stressed that it participates in arch rib again; The load action of main span bridge deck passes on main arch rib and the bridge tower by suspension rod and suspension cable in the main arch scope, and the power on the bridge tower is directly passed to bridge pier, and the power in the main arch rib is compiled at arch springing, passes to bridge pier by arch springing again.
This rope arch that tiltedly draws arch composite bridge innovative technology key to be to give full play to cable stayed bridge and arch bridge interacts, common stressed characteristic, has embodied following structural advantages:
(1) suspension cable can improve the structure span ability as the elastomeric bearing of structure, can adjust the moment of flexure of main arch and side bar by suitable Suo Li.The existence of suspension cable can improve the rigidity of main arch structure, has increased the span ability of main span and end bay.
(2) with the span arch compare, because suspension cable can avoid being provided with spandrel column to the supporting role of beam portion.The suspension cable that acts on the arch can be born load jointly with main arch, reduces
The horizontal thrust of main arch, the integral rigidity of raising structure, the stability of enhancing full-bridge has played the optimization function to main arch.
(3) with the span cable stayed bridge compare, because main arch has born part bridge floor load, can reduce stay cable force, it is long to have shortened inclined cable, reduces the suspension cable radical, has reduced tower height.Simultaneously because the effect of limit arch can avoid being provided with auxiliary pier.
(4) for construction, bridge tower is permanent force structure, as the support system of knotted rope pylon and cable lifting pylon, has reduced the difficulty that structure is implemented in can constructing again; Suspension cable can have the effect of interim knotted rope concurrently, has reduced the construction gadget, has reduced construction costs.
(5) tiltedly draw the arch bridge modern design attractive in appearance, peculiar, have abundant landscape effect, can be used as the landmark building in city.
Result of study shows that this combination bridge-type structural bridge has good stress performance and rational technical-economic index.This bridge type is world's initiative, and modern design is attractive in appearance, has abundant bridge landscape effect, will promote the development of modern bridge.
And tiltedly draw the arch combined system to combine the characteristics of arch bridge, cable stayed bridge, suspension cable is pulled on the arch, forms the common stressed novel arch bridge that tiltedly draws of rope arch, the existence of arch has increased the rigidity of diagonal bridge, reduce the long and rope number of Suo Li, rope of suspension cable, reduced tower height.Simultaneously because the effect of limit arch can avoid being provided with auxiliary pier.The existence of king-tower can also reduce the difficulty that structure is implemented as the support system of knotted rope pylon and cable lifting pylon in construction.Suspension cable assists main arch stressed, plays the effect of adjusting the arch rib axis, improving the rigidity of structure and reduce main arch thrust.Compare with encircleing, because suspension cable can avoid being provided with spandrel column to the supporting role of beam portion with span.This new bridge type has originality, is blank at home and abroad.
