It is a kind of cable carrying bogie that composite bridge is tiltedly drawn in suspention.Owing to suspend, tiltedly draw two-part being used in combination in midair, make it possess plurality of advantages: to suspend in midair, tiltedly draw two parts girder can adopt different materials, adopt prestressed steel reinforced concrete beam or bondbeam as oblique pull portion, foil portion adopts girder steel etc., structural performance be can improve, beam, cable, anchorage material usage reduced; The minimizing of foil portion girder length also can reduce main rope power, reduces the anchorage construction difficulty, thereby makes the enforcement of suspended-cable structure on soft foundation become possibility; Tiltedly pull portion adopts prestressed steel reinforced concrete beam or bondbeam, and weight and rigidity strengthen, and can also improve structure construction and the wind resisting stability that becomes the bridge state.Thereby, frequently proposed in the bridge scheme that this kind bridge type scheme is established all over the world.Because theoretical side is immature, structure detail is handled many reasons such as unreasonable, and many co-operative system schemes are finally replaced by single suspension bridge or single cable stayed bridge scheme.
Tiltedly draw combination bridge for suspention, how effectively to control main span suspention under the load action, tiltedly draw intersection not have the geometry linear of hoist cable district main push-towing rope, the rigidity how the reasonable coordination load action suspends in midair down, tiltedly draws intersection's girder is the difficult problem that the puzzlement industry is solved for many years and not conscientiously.Can whether above-mentioned two difficult problems can be properly settled, be related to whole suspention and tiltedly draw the combination bridge successful implementation, and lot of domestic and foreign scholar and engineers and technicians have done a large amount of research, but all do not find rational solution.
Wherein, the people who propose to adopt many modes to suspension rod and oblique cord arranged crosswise to solve the problems referred to above is more.Adopt many modes to suspension rod and oblique cord arranged crosswise, can make under the load action, suspention and oblique pull portion girder rigidity are coordinated to a certain extent, but under oblique cord partial action vehicular load operating mode, the cross section suspension rod can significantly unload, even deactivate, the fatigue problem of suspension rod is particularly outstanding; Otherwise under foil portion effect vehicular load operating mode, the cross section oblique cord also fatigue problem can occur.In addition, many employings to suspension rod and oblique cord arranged crosswise mode do not have the control of the geometry linear of suspension rod district main push-towing rope and contribute very little to main span.
Owing to adopt and many suspension rod and oblique cord to be intersected and the mode of beam structure layout entirely, thus over head and ears theoretic mistaken ideas and can not extricate oneself, so the kind scheme can not be implemented always.
Summary of the invention
The objective of the invention is at above-mentioned present situation, it is reasonable to aim to provide a kind of structural system, structure detail is handled ingeniously between steel case beam and prestressed reinforced concrete case beam or the bondbeam, and power transmission is reliable, durable to be suitable for, combination bridge is tiltedly drawn in a kind of suspention of economical rationality.
The implementation of the object of the invention is, combination bridge is tiltedly drawn in a kind of suspention, establish suspension cable between the prestressed reinforced concrete case beam of bridge tower and oblique pull portion or bondbeam, it is fixing on the bridge tower top that two ends are anchored in the main push-towing rope of anchorage, stride in main push-towing rope and the foil portion between the steel case beam conventional suspension rod is arranged, suspention tiltedly draws intersection to adopt low strain pull bar, in stride and adopt movably between steel case beam and oblique pull portion prestressed reinforced concrete case beam or the bondbeam that hinged bearing is connected.
Suspention of the present invention tiltedly draws combination bridge that following advantage is arranged:
1,, can effectively control main span suspension cable, two ends under the load action and do not have geometry linear in the face of hoist cable section main push-towing rope, thereby avoid the appearance of the instability problem of main push-towing rope in face in suspention, tiltedly draw intersection to adopt low strain pull bar; Can effective coordination suspention, tiltedly draw the rigidity of intersection's girder, avoided suspention fully, tiltedly drawn the suspension rod of the vicinity that crosses, oblique cord tired condition to occur;
2, in stride steel case beam hinged bearing be connected with tiltedly adopting movably between pull portion prestressed reinforced concrete case beam or the bondbeam, can eliminate the mobile load hogging moment and just temperature Change to the adverse effect of structure;
3, structural system is reasonable, and CONSTRUCTED SPECIFICATION is handled proper, and economic advantages are obvious, compares with the suspension bridge of striding the footpath on an equal basis, can significantly reduce the material usage of main push-towing rope, anchorage structure;
4, by optimizing the beam length of foil portion, reach the purpose that reduces main push-towing rope and anchorage scale, thereby make the consumption of material be saved economical rationality;
5, scientific and reasonable for structure, power transmission is reliable, durablely be suitable for, safety economy.
