Z-shaped bridge end transition slab structure and construction method thereof
The invention relates to a Z-shaped bridge end transition slab structure. The Z-shaped bridge end transition slab structure comprises a Z-shaped transition slab main body arranged in embankment fill; the Z-shaped transition slab main body comprises an upper plate, a sloping plate and a lower plate in sequence from top to bottom; and the end part of the upper plate far away from the sloping plate is connected with a bridge main girder in a longitudinal direction. The invention further relates to a construction method for the Z-shaped bridge end transition slab structure. According to the Z-shaped bridge end transition slab structure provided by the invention, as the stiffness of the Z-shaped transition slab main body is gradually changed from the main girder, to the upper plate, to the sloping plate, to the lower plate and to an approach pavement, a problem of stiffness abrupt change in the traditional transition slab is solved. As a method used by the Z-shaped transition slab main body to absorb and transmit longitudinal deformation of the main girder is between a transmission type transition slab and an absorbing type transition slab, the restraint stiffness of the Z-shaped bridge end transition slab structure is enhanced and an overlong transition slab and excessive pre-splitting cracks are not needed. As the Z-shaped transition slab main body can be adjusted according to needs to adapt to the needs of different bridges, the Z-shaped bridge end transition slab structure provided by the invention exerts good applicability and can be widely applied to the field of bridges, in particular non-crack bridges.
