Bridge abutment structure and control method capable of preventing bumping at bridge head

Abstract

The invention relates to a bridge abutment structure and a control method capable of preventing bumping at a bridge head, and belongs to the technical field of bridge engineering. According to the technical scheme, the bridge abutment structure capable of preventing the bumping at the bridge comprises a bridge, bridge piers and bridge abutments, wherein the bridge piers are positioned below bridgeend heads, the bridge abutments are assembled on the bridge piers; the bridge abutments comprise horizontally distributed abutment caps and back walls perpendicular to the abutment caps, end head supports used for supporting the bridge end heads are arranged on the abutment caps, the back walls are located on the outer sides of the bridge end heads, and the back walls are attached to subgrade; and the height of a bridge deck of the bridge end heads can be reduced by reducing the height of the end head supports, after the end head supports and the back walls are reduced to the same height, theheight of the bridge deck of the bridge end heads and the height of the tops of the back walls are located on the same horizontal plane so as to prevent the bumping at the bridge head. According to the structure and the method, the settlement difference between the bridge and the pavement is eliminated by adjusting the height of the back walls and the height of the end head supports, so that theproblem of bumping at the bridge head is solved.

Description

technical field [0001] The invention relates to an abutment structure, in particular to an abutment structure capable of preventing vehicle jumping at the bridge head and a prevention and control method, belonging to the technical field of bridge engineering. Background technique [0002] According to the "Statistical Bulletin on the Development of the Transportation Industry in 2014" issued by the Ministry of Transport, by the end of 2014, the total mileage of highways was 4.4639 million kilometers, of which 111,900 kilometers were highways. However, there were many diseases in its operation. Bridge head jumping is one of the common problems that have not been well resolved. The bridge head abutment is located at both ends of the bridge and is used to support the bridge superstructure and connect the embankment. The abutment consists of a horizontally installed platform cap and a vertical Composed of the back wall, the bridge is supported by reinforced concrete bearings on ...

Problems solved by technology

[0009] Although the application of one or more of the above methods can alleviate the phenomenon of vehicle jumping at the bridge head to a certain extent, the stiffness difference between the bridge and the road cannot be eliminated, and differential settlement still exists. Therefore, the above methods cannot fundamentally solve the problem of bridge head jumping. car problem
