Description
Technical field
The present invention relates to a kind of bridge, particularly a kind of self-anchoring type suspension cable-oblique pull co-operative system steel structure bridge.
Background technology
Since the nearly century, the development of bridge engineering achieves huge achievement, and wherein the system of cableway platform develops and the breakthrough of span is exactly wherein one of most important achievement.So-called cableway platform, refers to using cable (main push-towing rope of suspension bridge) or rope (drag-line of cable stayed bridge) as the bridge of main supporting member.Cableway platform has two important features: one be main bearing member to bear axial force, cable, rope bear axial tension, and the stiff girder of cable stayed bridge, self-anchored suspension bridge and bridge tower are based on pressurized; Two be cable as main bearing member, adopt high-strength material (being generally high-tensile steel wires) to make, tensile strength is large, from heavy and light.Therefore, compared with other bridge type, cable bearing system bridge is more suitable for large span future development.And in fact, for the bridge across footpath scope of 200-1500 meters (even larger), cable carrying bogie has competitiveness, cable carrying bogie approximately account for 200-1500 meters across 5/6 of bridge quantity total within the scope of footpath, for now, the common structure pattern of cableway platform mainly contains suspension bridge and cable stayed bridge.
Cableway platform is except above-described suspension bridge and cable stayed bridge, and Abroad in Recent Years all proposes oblique pull-suspension cable co-operative system bridge scheme to a lot of Large Span Bridges engineering.Wherein many very excellent schemes of can yet be regarded as.Although China's starting is more late in oblique pull-suspension cable co-operative system bridge, but along with the development of China's communication, in recent years also repeatedly propose suspension cable-oblique pull co-operative system bridge scheme in domestic many engineerings, the suspension cable-oblique pull co-operative system bridge of the first in the world seat Modern Significance has also been built in Guizhou.
Suspension cable-oblique pull co-operative system bridge is a kind of novel cableway platform, and it is made up of several major parts such as stiff girder, king-tower, main push-towing rope, suspension cable, suspension rod, bases.When becoming bridge, jointly bear deadweight and the external load of structure primarily of main push-towing rope, suspension cable, stiff girder and king-tower.Cable is the main supporting member in structural system, is geometrically unstable system, bears pulling force effect.Cable not only can be out of shape by natural resiliency affects system balance, and can affect system balance by the change of its geometry, and show the nonlinear mechanical characteristics of Large travel range, this is one of key character of suspension cable-oblique pull co-operative system bridge.The cable of suspension cable-oblique pull co-operative system bridge has very large initial tensioning force under dead load, provides powerful gravity stiffness to subsequent structural.This is the basic reason that suspension cable-oblique pull co-operative system spanning footpath is able to continuous increase, stiff girder rise-span ratio is reduced.
Suspension cable-oblique pull co-operative system bridge is generally divided into ground anchor type and self-anchoring type two kinds of systems.
(1) ground anchor type suspension cable-oblique pull co-operative system bridge, as shown in Figure 1a.
This co-operative system bridge needs to build huge anchorage, and main push-towing rope vertical force component and horizontal component are passed to basis.Under the environment that foundation condition is good, self-anchoring type suspension cable-oblique pull co-operative system bridge can be paid the utmost attention to.
(2) self-anchoring type suspension cable-oblique pull co-operative system bridge, as shown in Figure 1 b.
This co-operative system bridge is anchored in stiff girder beam-ends main push-towing rope, and stiff girder also bears the huge axial compression that main push-towing rope and suspension cable transmit except bearing moment of flexure, and there is beam-post effect, structure has obvious geometrical non-linearity feature.Vertical force component is born (vertical force component passes to bridge pier by tension compression bearing) by counterweight and bridge pier, and this system is due to without the need to huge anchorage, and therefore, in soft soil areas, high wind area etc. has very strong superiority.
Self-anchoring type suspension cable-oblique pull co-operative system bridge, girder total weight is passed to girder and king-tower by suspension rod, main push-towing rope and suspension cable by usual employing, girder bears this huge axial pressure, along with the increase across footpath, because girder is from great, girder axle power can be caused excessive, bring the danger of overstep the extreme limit supporting capacity and unstable failure.
Summary of the invention
The present invention provides a kind of self-anchoring type suspension cable-oblique pull co-operative system steel structure bridge for solving in known technology the technical problem that exists, and this bridge can reduce the axle power of girder, and then avoids girder supporting capacity to transfinite and the danger of unstable failure.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is: a kind of self-anchoring type suspension cable-oblique pull co-operative system steel structure bridge, comprise king-tower, end bay bridge pier, girder, main push-towing rope, suspension cable and suspension rod, described girder is supported by described king-tower, described end bay bridge pier, described main push-towing rope and described suspension cable, the middle part of described girder be connected with described main push-towing rope by described suspension rod, described girder is steel-structure box girder.
The advantage that the present invention has and good effect are: by adopting structure steel box-girder being applied to self-anchoring type suspension cable-oblique pull co-operative system bridge, solve the problem that Long span self-anchoring type suspension cable-oblique pull co-operative system bridge bridge main beam axle power is excessive.And adopt girder steel as girder in the present invention, this dead load is light, and span ability is strong, and speed of application is fast.
