Abstract
The monitoring system comprises an ultra-weak fiber grating cable, an ultra-weak fiber grating array is written in the ultra-weak fiber grating cable, a plurality of fixed points are arranged on the ultra-weak fiber grating cable at equal intervals, the ultra-weak fiber grating cable is fixed on the reinforcement cage of the measured bored pile through the fixed points, the ultra-weak fiber grating cable is connected with an ultra-weak fiber grating demodulation module, and the ultra-weak fiber grating demodulation module is wirelessly connected with a cloud server. The application introduces the ultra-weak fiber grating uwFBG into pile foundation strain monitoring, and proposes an online monitoring system and method for the bored pile based on the ultra-weak fiber grating. The monitoring system can effectively improve the monitoring capacity of the pile foundation sensing system, can realize online monitoring of the bored pile, and widens the application field of the ultra-weak fiber grating.
