Description
Technical field
The utility model relates to bridge structure, and particularly a kind of passenger dedicated railway line is crossed over the LONG-SPAN RAILWAY deck type concrete arch-type bridge structure of mountain area " V " type Valley.
Background technology
The passenger dedicated railway line bridge is higher to rigidity requirement, and in each long span bridge type, cable stayed bridge and suspension bridge are because himself rigidity is difficult to promote, and temperature deformation is large, and difficulty satisfies the related request that train is runed at a high speed.And arch bridge not only has larger span ability and integral rigidity as a kind of bridge type commonly used, and can well combine with Valley.Concrete arch-type bridge particularly has that rigidity is large, supporting capacity strong, is subjected to that influence of temperature change is little, cost low and the plurality of advantages such as the late maintaining maintenance load is little, emphasizes the characteristics just coincide that the rigidity of structure and distortion are little with the passenger dedicated railway line bridge.Different from the position of arch ring according to bridge deck, arch bridge can be divided into deck type, half-through, three kinds of forms of lower support type, and present built large-span concrete arch bridge mostly is the deck type fixed-end arch, and mostly is ribbed arch, adopts the less of plate arch.And at present the concrete box shaped slab arch bridge of deck type is and waits the width arch, i.e. main arch cross section employing is wide.The railroad bridge bridge floor is often narrower, and the main arch ring width needs to coordinate mutually with it, and lateral stiffness is subject to certain limitation, although still can satisfy the requirement of little span Lateral Stiffness of Railway Bridge, is difficult to adapt to the requirement of railway wide span bridge lateral stiffness.Be to improve the railway wide span bridge lateral stiffness, guarantee the safety of operation condition Train and take passenger's comfortableness, need increase arch ring width, such as the arch ring widen out, because bridge floor is narrower, spandrel structure and main arch ring inaccurate coordination affect the Bridge Landscape effect; And increased main arch bricklaying consumption, caused the waste of material.And for spandrel structure, the spandrel structure of China's deck type concrete arch-type bridge all adopts the freely supported structure system, because the simply supported beam span ability is limited, along with the increase of arch bridge span, spandrel column is higher, (be the 500m arch bridge such as span near the 1# pier stud of arch springing particularly, ratio of rise to span adopts 1/5, and the 1# column is near 100m on the arch), on the arch pier stud longitudinal rigidity difficulty meet design requirement, and spandrel column is many, has increased difficulty of construction and construction risk.
The utility model content
The utility model wants the technical solution problem to provide a kind of LONG-SPAN RAILWAY deck type concrete arch-type bridge structure, satisfy well arch bridge structure laterally, longitudinal rigidity and stressed in, can reduce difficulty of construction and the construction risk of main arch ring and spandrel structure, and greatly reduce construction costs.
The technical scheme in the invention for solving the technical problem is as follows:
LONG-SPAN RAILWAY deck type concrete arch-type bridge structure of the present utility model, comprise main arch ring, boundary pier, arch upper beam, spandrel column and abut basis, boundary pier and main arch ring both sides arch springing are supported on the abut basis, arch is put the beams in place and is supported on the main arch ring by spandrel column, it is characterized in that: described main arch ring is contour single-box multi-cell cross section box-shaped plate arch, its dome portions is wide section, is the linearity section of broadening near both sides arch springing section; Described boundary pier consists of boundary pier T structure with the T structure beam that is consolidated in its top, and described arch is put the beams in place and is continuous beam on many supports.
The beneficial effects of the utility model are, main arch arch springing part broadens and well adapted to span and change the requirement of main arch lateral stiffness, and structure stress is reasonable, and is safe and reliable; Guaranteeing arch bridge structure vertically, under the prerequisite of lateral stiffness and force request, reduced difficulty of construction and the construction risk of structure, the main arch section can form stage by stage, significantly reduces the construction costs of this bridge construction, reduces investment outlay; And bridge good looking appearance, arch upper span ratio and main arch scale coordination are rich in the rhythm, and the deep valley landform is combined with the mountain area, has stronger visual impact, and landscape effect is splendid, can demonstrate fully the aesthetic effect of bridge.
