The invention discloses a novel
integral abutment bridge with a dog-bone shaped connecting structure and construction method. The bridge comprises an end beam, a
pile cap and an H-shaped supporting steel
pile; a weak shaft of an H-shaped steel
pile body is bent; the
pile cap is connected with the end beam by the dog-bone shaped connecting structure, wherein the dog-bone shaped connecting structure is that a compressing
rubber material fills in a connecting clearance between the
pile cap and the end beam, and the
pile cap and the end beam are connected through the H-shaped steel pile. According to the bridge, the H-shaped steel pile can bear the
vertical load through the
surface friction and even the end part, and moreover, the characteristics that the lateral rigidity of the weak shaft is low is utilized well; the rigidity of the connecting part is reduced by the dog-bone shaped connecting structure between the pile cap and the end beam, thus the rotating capacity of the connecting part is improved, the
longitudinal deformation capacity of the bridge is increased, the allowable length of the bridge of the type is raised, a pile foundation is avoided excessive
lateral displacement, the vertical
bearing capacity of the pile is ensured, the internal force of the pile body is decreased, the
fatigue damage of the temperature deformation of the bridge to the pile body is reduced, and as a result, the service life of the bridge is prolonged.
