摘要

A robust embeddable Fiber Bragg Grating based sensing cable has been developed by Monitor Optics Systems. This sensor sees an array of Bragg Gratings encapsulated in a pultruded Glass Fiber Reinforced Polymer rod. The sensors are easy to install and more robust than telecom standard optical fibers and can be used in a number of different applications. An example is illustrated where the sensors have been used to instrument a section of a main highway in Australia to measure ground strains in the road pavement as part of a pavement monitoring system. The monitoring system is being used to monitor the effects of mining induced subsidence on the road as the main component of an early warning safety system. The monitoring system has been continuously expanded over the last 3 years in accordance with the advancement of the mining activity and now fields over 800 Fiber Bragg Gratings. The system proved to be reliable and accurate and is now the primary tool for alarm triggering and response. The sensing cables are now being used to monitor instability in embankments.
