Method and intelligent force-measuring supporting seat for monitoring bridge health

Abstract

The invention relates to a method for monitoring bridge health. According to the method, a plurality of plate type rubber supporting seats are adopted, wherein a force measuring element is arranged on each plate type rubber supporting seat, and comprises a plurality of optical fiber strain sensors for sensing the axial pressure and the shearing force on a corresponding supporting seat; the optical fiber strain sensors are symmetrically arranged in corresponding plate type rubber supporting seats, and are connected to an optical fiber data acquisition converter which converts an optical signal into an electric signal and displays the electric signal in the form of strain; and the average value of read numbers of the optical fiber strain sensors, which is acquired by the optical fiber data acquisition converter, is used as a final supporting seat stress strain measurement value. The invention also relates to an intelligent force-measuring supporting seat for monitoring the bridge health. According to the method and the intelligent force-measuring supporting seat for monitoring the bridge health, the stress condition of a bridge supporting seat can be accurately and effectively monitored, the shape of the supporting seat is not different from a common supporting seat, and the supporting seat can be conveniently manufactured and mounted, so that the method and the supporting seat can be used for tracking and monitoring construction loads, vehicle overload and abnormal changes of bridge performance of a bridge in real time.

Description

technical field [0001] The invention relates to a bridge health monitoring method and an intelligent force-measuring bearing thereof, which are suitable for monitoring bridges and other engineering structures. Background technique [0002] For a long time, the monitoring of bridge bearings has been mainly carried out through traditional manual and visual inspection methods, such as inspections with the help of simple tools such as telescopes. Generally, it is necessary to go to the bridge under the bridge or use a high-cost bridge monitoring vehicle for inspection. Due to the high pier abutment and the small clearance between beams, slabs and pier abutment, the detection work is not only very inconvenient, but also has certain dangers. The most important thing is that this detection method cannot determine the actual working performance of the bearing, nor can it monitor the stress situation of the bearing or even the health status of the bridge structure.
