ABSTRACT
When the bridge splicing connection is carried out without interrupting the traffic, the differential vibration deformation will occur at the splicing position under the action of vehicle-bridge coupling vibration. It will affect the long-term performance of splicing joints. Therefore, it is necessary to develop a new type of concrete material that can satisfy the requirements of shear deflection and vibration disturbance. Combined with the vibration monitoring and simulation of the actual bridge, the vibration characteristics of the existing old bridge are analyzed to obtain the development requirements of anti-differential disturbance concrete. The vertical shaking table was applied to test the performance of proposed material. After the implementation in the widened bridge, a standardized pouring process for anti-differential disturbance concrete was formed. A series of detection methods were proposed as well. The complete set of construction technology and quality inspection technology of the anti-difference disturbance concrete are established.
