The prestressed concrete continuous rigid-framed bridge system has characteristics such as integrality performance of the structure is good, anti-seismic performance is strong, structure stress is reasonable, bridge type brevity and lucidity, at home and abroad is widely adopted in the engineering practice.External as the Gateway road bridge of Australian main span 260m and the Douro double track railway new bridge of Portugal main span 250m etc.; The auxilliary navigation channel of the Humen, the Guangdong highway bridge of domestic main span 270m bridge, and building main span 268m Soviet Union logical special purpose channel bridge, the main span 260m Chongqing Yu Dong Yangtze Bridge and main span 330m Chongqing slabstone Ramp bridge (main span is steel one a prestress concrete combined system) etc.Limited by the strictness of each side such as railroad bridge train load, travel safety and passenger's riding comfort, railway continuous rigid frame bridge span is all less, what build and built single track bridge such as main span 168m Panzhihua special purpose railroad Jinsha jiang River bridge, the railway main span 128m of Nanning-Kunming clear water river bridge and Wenzhou-Fuzhou railway main span 145m Baima river bridge and suitable river, ten thousand railway 128m ferries bridge double track bridges is arranged.But, being subjected to concrete shrinkage, creeping and factor affecting such as load, the problem of span centre downwarp has appearred in many big span continuous rigid structure bridges in various degree in the operation, perplexed super large and striden further developing of prestressed concrete continuous rigid frame.
Only tower tiltedly draws the continuous rigid frame composite bridge will stride the prestressed concrete continuous rigid frame greatly and two kinds of structural systems of cable stayed bridge organically combine, and has well solved many key technologies such as the rigidity of structure, train traveling, wind resistance shock resistance, anti-fatigue performance.The deadweight of beam body is mainly born by beam portion, and suspension cable assists kingpost cantalever to build in the work progress, bears the part dead load, and the second stage of dead load and mobile load are born jointly by the combination bridge architecture.By the booster action of suspension cable, improved whole TERM DEFORMATION of continuous rigid frame and stress, thereby guaranteed that the beam body is linear span centre.
Have not yet to see the correlative study report that only tower tiltedly draws the continuous rigid frame composite bridge, only, tiltedly draw a T structure co-operative system but be only tower at the similar bridge of the main span 283m Xijiang River, Zhaoqing, Guangdong bridge and Panzhihua main span 200m Jinsha jiang River, Sichuan bridge.
Summary of the invention:
The purpose of this utility model is to organically combine striding two kinds of structural systems of prestressed concrete continuous rigid-framed bridge and cable stayed bridge greatly, form new only tower and tiltedly draw the continuous rigid frame composite bridge, make 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: solely tower tiltedly draws the continuous rigid frame composite bridge, comprises girder 1, Sarasota 2, suspension cable 3, side main pier 4 and main pier 5, it is characterized in that described girder is a prestressed concrete continuous rigid frame structure; Be provided with the suspension cable that is connected with the girder of Sarasota the right and left respectively at Sarasota the right and left; Described Sarasota, girder and main pier are rigidly connected mutually, and side main pier and girder are rigidly connected.
In such scheme, described suspension cable and Sarasota and girder connected mode can be single rope face or two rope face form.
In such scheme, described Sarasota can be concrete or steel work bridge tower.
The utility model mainly is based on main beam stress, is aided with the stressed combined structure system of suspension cable.The deadweight of beam body is mainly born by beam portion, and suspension cable is assisted the kingpost cantalever construction in the work progress.Solely tower tiltedly draws continuous rigid frame composite bridge innovative technology key to be to give full play to the interaction of continuous rigid frame and two kinds of systems of cable stayed bridge, common stressed characteristic, has embodied following structural advantages:
(1) compare with general cable stayed bridge, girder has bigger deck-molding and rigidity, distributes bigger load and internal force, and the inclined cable stress amplitude is less, does not have fatigue problem substantially, is a kind of reinforcing beam flexible cable system.
