Abstract: Disclosed are an easily maintainable assembly-type bridge expansion joint structure and a construction method thereof. The easily maintainable assembly-type bridge expansion joint structure, comprising: a to-be-connected bridge beam end, wherein a number of the to-be-connected bridge beam end is two, and a groove platform is provided on each of the two beam ends in an extending direction of a gap; a connecting box body, wherein a number of the connecting box body is two, each of the two connecting box bodies is fixedly arranged on the groove platform of the beam end, and a box chamber is provided on opposite side surfaces of the two connecting box bodies respectively, a plurality of box chambers are provided, which are open opposite each other, and the box chamber is provided in the extending direction of the gap; a side beam, wherein a number of the side beam is two.

Abstract: The present disclosure provides an automatic test system for actual stress of a bridge based on DIC technology, where the system includes a camera, a phosphor spraying device, a computer, and a sliding rail; the sliding rail is arranged on both sides of an upper wing of a box-shaped concrete beam; the phosphor spraying device is used to spray phosphor on a web of the box-shaped concrete beam to form speckles of varying light and shade; the camera is slidably connected to the sliding rail through a bracket, and is used to photograph the speckles and transmit a speckle image to the computer; and the computer is used to analyze and process the speckle image taken by the camera and generate a time history diagram of stress.
