Background

The bridge support is an important component and device for realizing load transfer, coordinated deformation and structural safety guarantee between the upper part and the lower part of the bridge, is critical in position and weak in structure, can directly cause stress deviation or unbalance of the lower part structure of the bridge due to damage or destruction of the bridge support, further causes damage and destruction of other components, accelerates the attenuation of the service life of the bridge, and directly threatens the overall safety of the bridge structure. With the development of economy and the increase of traffic volume, the damage or destruction of a bridge support becomes one of main diseases of an active bridge in China, regular manual detection is a common means for obtaining the health condition of the bridge support at present, but in view of the fact that the bridge support is generally in a severe and concealed engineering environment, the limitation of a manual detection method causes that many diseases cannot be found and treated in time. Therefore, the intelligent support with the functions of remote real-time monitoring and early warning is researched and developed, the health condition and potential risks of the service support and the bridge can be mastered in time, and the local or overall damage of the bridge caused by the sudden damage of the bridge support is avoided. That is, the intellectualization of the bridge support can prevent bridge accidents caused by support damage in the bud, and also can provide reliable data for health monitoring and diagnosis of the superstructure and construction of an intelligent transportation system.

The three-way force-measuring support is provided with a force-measuring element and data acquisition and processing equipment on the basis of a conventional support, but the support structure is greatly modified due to the selection of the type of a sensor.

A support capable of measuring vertical displacement and load based on a fiber grating sensor is developed by Sung-JinChang and Nam-SikKim, is used for controlling errors in the installation process of a bridge support, and long-term monitoring is not achieved. Dong-HoHa et al propose that the load is measured by putting a piezoelectric material in the support and collecting energy, so as to monitor the traffic flow and the support stress, and the monitoring target is single.

In the prior art, the monitoring of the stress condition of the support mainly depends on a pressure sensing unit, and data information of the pressure measured by the sensing unit needs to be led out through a lead, so that micropores need to be formed in the support for leading out a lead, and further the overall mechanical property of the support is affected; in addition, the replacement of the sensing unit is also a difficult problem in the current technical field of the support, and due to the fact that the sensing unit is usually fixedly connected with the support body, if the sensing unit needs to be replaced, the whole support needs to be replaced, so that the cost is high, and the operation is complex.
