Bridge Foundation Scouring Monitoring Sensor and Monitoring Data Analysis Method Thereof
The disclosure provides a bridge foundation scouring monitoring sensor and a monitoring data analysis method thereof, and belongs to the technical field of bridge engineering. The disclosure solves the problem that an existing bridge foundation scouring monitoring technology cannot realize reliable, efficient and high-precision bridge foundation scouring depth monitoring. The bridge foundation scouring monitoring sensor comprises a cover plate, a lower fixing unit and scouring depth monitoring standard units fixedly disposed between the cover plate and the lower fixing unit. Each scouring depth monitoring standard unit comprises a supporting frame and an optical fiber vibration string disposed in the supporting frame; the upper end and the lower end of each optical fiber vibration string are both fixedly connected with the corresponding supporting frame; a plurality of polyhedral mass blocks are evenly distributed on each optical fiber vibration string from top to bottom; and a fiber Bragg grating is disposed at the upper portion of each optical fiber vibration string. The bridge foundation scouring monitoring sensor of the disclosure realizes long-term real-time monitoring on the scouring depth of a bridge foundation and has higher monitoring efficiency and reliability compared with the current monitoring technology.
