Bridge deck fatigue crack monitoring method, device and system
The invention discloses a bridge deck fatigue crack monitoring method. The method comprises the following steps: setting a plurality of monitoring areas on a bridge, and collecting potential difference data in each monitoring area; wherein each piece of potential difference data comprises a plurality of potential differences, and each potential difference corresponds to one acquisition moment; respectively calculating a crack value corresponding to each monitoring area according to the corresponding potential difference data in each monitoring area; and generating crack value curves in one-to-one correspondence with the monitoring areas according to the crack values and the acquisition moments in the potential difference data, and determining the monitoring area where the fatigue crack is located according to the crack value curves. According to the invention, manual on-site patrol can be replaced, on-site real-time monitoring of bridge deck fatigue cracks is realized, hidden cracks in an early development stage are identified in time, and the fatigue crack monitoring efficiency is improved.
本发明公开了一种桥面疲劳裂缝监测方法包括：在桥上设置若干个监测区域，采集各监测区域内的电位差数据；其中，每个电位差数据包括若干个电位差，且每个电位差对应一个采集时刻；根据各所述监测区域内对应的电位差数据，分别计算各所述监测区域对应的裂缝值；根据各所述裂缝值和各电位差数据中的采集时刻，生成与各所述监测区域一一对应的裂缝值曲线，并根据各所述裂缝值曲线，确定疲劳裂缝所处的监测区域。本发明能代替人工现场巡查，实现现场实时监测桥面疲劳裂缝，对内部处于早期发展阶段的隐蔽裂缝进行及时识别，提高了疲劳裂缝监测的效率。
