Problems solved by technology

[0005] For the transverse bridge direction, the soil behind the abutment is basically unable to play a role, and the first-order mode shape of the overall bridge is generally transverse bridge direction, so the transverse bridge direction damage of the pile foundation and abutment is more likely to occur under earthquake action

Abstract

The invention relates to a self-resetting integral type flexible abutment. The self-resetting integral type flexible abutment is characterized by comprising a main beam, a guide plate and a wiring pavement which are arranged in sequence, wherein a main bridge abutment and a bearing platform are sequentially arranged between the main beam and the guide plate from top to bottom, a secondary bridge abutment is arranged between the guide plate and the wiring pavement, the main bridge abutment and the secondary bridge abutment below the guide plate and the wiring pavement are respectively providedwith backfill, the main bridge abutment and the bearing platform are pulled into a whole through prestressed tendons, and angle steel is screwed at the joint of the main bridge abutment and the bearing platform. The self-resetting integral flexible abutment is simple in structure.

Description

technical field [0001] The invention relates to a self-resetting integrated flexible abutment and its application. Background technique [0002] The seismic problem of bridges has always been the focus of engineering and academic circles. Although bridge design codes in various countries have detailed seismic design methods and requirements, there are still many bridge failures and collapses in each earthquake. my country is an earthquake-prone country with frequent earthquakes and strong magnitudes. Seismic activity is mainly distributed in the southwest, northwest, south China and the Taiwan Strait, and there are many bridges in these places. Although the seamless bridge has better seismic performance than the slotted bridge, the research on its seismic performance is still a very important subject. [0003] The upper and lower structures of the overall bridge are connected as a whole, without expansion joints and supports, and the abutment adopts a flexible foundation,...
