The invention is characterized in that the bridge comprises a serial combination of diagonal cable-stayed sections (4) and a suspension bridge part (5), the main suspension cable (2) being comprised of at least one centric main suspension cable, the bridge deck (6) comprising two or more separate decks arranged with constant or varying distance there between, the two or more bridge deck being connected with crossbeams (7) or other strutting, the diagonal cable-stays (8) and suspension hangers being fixed to the crossbeams or other strutting or the bridge decks, the suspension hangers, main suspension cable and the crossbeams or other strutting forming a triangular structural system in a vertical plane transversely of the bridge.
Description
The present invention relates to span and surpass about 500 meters bridge, described bridge has constituted an alternative to conventional suspension bridge and cable stayed bridge.
Up to today, have only suspension bridge to be used for surpassing 1000 meters span, and worldwide built the bridge that many span scopes are 1000-2000 rice.Typical suspension bridge comprises from two parallel hanging pulls a center bridge of suspension, and the vertical suspension between bridge and the messenger cable.Messenger cable is supported by each terminal tower of spanning degree, and it continues to cross these towers, finally grappling in rock or concrete foundation.Tower is typically designed to A font or H font, and tower has a pillar in every side of center line road and bridge beam, and crossbeam between pillar, that be lower than and be higher than bridge.
For the situation of span above 1000 meters, eolian is architectural main load, and it is crucial selecting a kind of construction notion that makes bridge can resist wind-force, and building must be fabricated under all wind-force effect situations all stable aerodynamically simultaneously.These aspect final decisions the scope of the use of material, weight and cost.
For the situation of long span, when the general mood time influenced the dynamic characteristics and aerodynamic design of bridge, the dead weight amount of bridge construction became the main static load bigger than traffic loading.Along with span increases, traditional suspension bridge structure reaches a kind of dead weight amount and quality, and it has got rid of the realization of engineering on economics.For this problem is described, have duty ratio between bridge, messenger cable and the traffic loading of 1000 meters bridges in two tracks and be about 60/20/20%, but for similar 2000 meters bridges, corresponding digital is 55/35/10%.Total proportion that simultaneously will load is increased to 16 tons on every meter bridge from about 12 tons of every meter bridge.
Because surpassing cross-over connection 1000 meters, possible, unsurmountable cost, many spans also do not realize.The cost that reduces this structure will be very beneficial.This must be reached by the deadweight that reduces bridge, keeps its aerodynamics stability simultaneously.Also need and can build this structure with measurable and reasonable manner, described mode will meet the strict demand to health, environment and safety.
Be built in 19
ThWith 20
ThMany bridges in century use the combination of diagonal stay cable and hanging stick.Foremost is the Brooklyn Bridge, and it was finished in 1883, and span is 486 meters.Diagonal bar and suspension overlap whole span top, make it become the high redundancy static system.This structure rigidity cable stayed bridge system and flexible suspension bridge system being not that best mode combines.
Norw P NO107352 has instructed a kind of combination of diagonal bar and messenger cable, but it has track separately and is not the parts of central loading.
So-called mixing bridge has also been built, wherein will be combined near the suspension bridge of the diagonal bar of tower and span mid portion.Example is the Nagisia bridge (110 meters) of Algerian Sidi Me Cid pedestrian bridge (164 meters) and Japan.
Diagonal bar makes up with track that separates and the list-Ta of central authorities individually, is used for the Stonecutter bridge in Hong Kong, and its span is 1018 meters, but diagonal bar is arranged on the outside of bridge floor.If span is bigger, this structure types is will be more expensive and produce stability problem in building course.
The invention solves problem,, the oblique section of drawing and subsequently center suspended span degree are arranged thereafter, facilitate the more bridge floor of rigidity by the bridge floor that use to separate and wide air gap therebetween and near the cantilever concrete bridge section of tower about wind stability.The lateral stiffness of the distance decision bridge between the bridge floor.This distance is variable, and helps reducing the material and the quality of bridge.Such change is impossible to traditional suspension bridge structure in principle.And the bridge floor of separation and central tower, diagonal bar, central messenger cable and the combination of inclination hanging stick will form triangular structure, and it has increased the torsional stability of bridge floor in itself.The increase of torsional stability has improved the aerodynamics stability of bridge.
Needs about safety in building course, cantilever bridge section (cantilever concrete bridge and diagonal angle cable stayed bridge) is in architectural process, to experience the stability problem that increases gradually from a side, itself and unsupported length square proportional, and suspension bridge produces more stable structure, because messenger cable is at first put in place by the aviation rotary setting.Messenger cable is across to another tower from a tower, and helps resistance to overturning, and other parts such as suspension, bar and bridge girder section are the parts that assemble fast simultaneously with the cable rotation.
Near the bridge portion of tower, the cantilever concrete structure is the most cheap selection for, but this method only can provide very limited span (maximum span by cost determination is 400 meters).The diagonal member pulling method is some costliness to less span, but can be used for quite long span (maximum span by cost determination is a 1000-1200 rice).The suspension bridge method needs high relatively every the price of rice lattice for less span, but can be used for very long span.The long span of once building is 1991 meters (Akashi-Kaikyo) in 1998.The cost rate of suspension bridge increases greatly along with the increase of span, mainly is because the increase of main push-towing rope tonnage and the increase of wind stability problem.
The present invention has significantly reduced the construction cost for Long Span Bridge by using the series of combination of cantilever, diagonal stay cable and suspension bridge.Compare with pure suspension bridge or diagonal angle cable stayed bridge, this combination has caused the remarkable minimizing of material.
Purpose of the present invention can reach by the feature described in claim 1 feature clause.Further favorable characteristics and characteristic description are in relevant claim.
