Abstract

The invention relates to a bridge performance state monitoring system, method and device. The bridge performance state monitoring system comprises: a displacement sensor which is used for being fixedto a measurement point of a measured bridge, enabling a contact to be perpendicular to the horizon and downward, and measuring the downwarping displacement variation of the measurement point relativeto a measurement reference point; a tension line with one end that is fixedly connected with a pier on one side of the measured bridge, and the other end of the tension line is movably connected to apier on the other side of the measured bridge and straightened for providing a measurement reference point of the displacement sensor; a data acquisition module that is electrically connected with thedisplacement sensor and is used for acquiring the downwarping displacement variation; and monitoring equipment that is in communication connection with the data acquisition module, and is used for remotely receiving the downwarping displacement variation, calculating to obtain dynamic deflection data and a live load impact coefficient of the measured bridge according to the downwarping displacement variation, and determining the performance state of the measured bridge according to the dynamic deflection data and the live load impact coefficient. By using the method and system, measurement efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of bridge safety, in particular to a bridge performance state monitoring system, method and device. Background technique [0002] With the development of bridge safety technology, the monitoring methods of bridge safety in the application process are also constantly iterating. The deflection of the bridge is an important basis for evaluating the safety performance of the bridge. The deflection of the bridge is closely related to the bearing capacity of the bridge and the ability to resist destructive loads such as earthquakes. Therefore, the development and research of bridge deflection measuring instruments and equipment is of great significance for the acceptance of new bridges and the evaluation of the safety performance of existing bridges. The load test of the bridge is a method to determine the bearing capacity and safety of the bridge through the static load and dynamic load tests of the bridge. By ...
