Abstract

The invention provides a monitoring system for real-time evaluation of hinge joint performance of a fabricated beam bridge. The monitoring system is used for monitoring the hinge joint performance ofthe fabricated beam bridge in real time, and is characterized by comprising at least one pair of speed sensors, a sensor mounting mechanism and an evaluation early-warning device, wherein the at leastone pair of speed sensors are arranged on the two sides of a hinge joint of the fabricated beam bridge respectively, and each speed sensor has a respective sensor serial number; the sensor mounting is used for mounting speed sensors on the two sides of the hinge joint; the evaluation early-warning device is in communication connection with the speed sensors respectively; each speed sensor is provided with a speed signal acquisition part, a dynamic deflection signal conversion part and a sensor communication part; and the evaluation early-warning device is provided with a sensor information storage part, a relative displacement generation part, a hinge joint performance early-warning part and an evaluation side communication part.

Description

technical field [0001] The invention belongs to the field of bridge monitoring and relates to a monitoring system for real-time evaluation of hinge joint performance of assembled girder bridges. Background technique [0002] With the acceleration of urbanization in our country, more and more urban viaducts have been built in cities to ensure smooth and efficient urban traffic. The prefabricated girder bridge has become one of the most widely used bridge types for urban viaducts due to its advantages of simple design, quick construction, and clear structural force. Under the combined effects of increasing traffic throughput, external environment, and aging of its own materials, the hinge joints of prefabricated girder bridges are gradually damaged, and even the phenomenon of single-beam stress occurs, resulting in a decline in the structural performance of the bridge, which brings great harm to the safe operation of urban infrastructure Hidden danger. [0003] At present, t...
