Abstract

Taking the monitoring project of slope protection at Wuzhuaguan tunnel portal, Hejiaping segment of Yiwan railway as an example, through the analysis of mechanism of mechanical transmission and failure mode of component of flexible system for protecting slope, we put forward a kind of early warning and alarm system for railway slope protection based on Fiber Bragg Grating sensing technology. Compared with the conventional supervising techniques, the supervising system designed in this work possesses the merits of higher reliability, lower cost, easier to installation, fewer maintenance and so on. This early warning and alarm system can effectively enhance the protecting function of disaster prevention and reduction for railway slope protection.
