Experimental research on safety monitoring based on FOS for high-speed railway infrastructure

This paper focus on the feasibility of preventing disaster by applying fiber optic sensing （FOS） technology to monitor safe conditions of infrastructures such as track, subgrade, bridge, tun- nel, slope and culvert. The Model experimental study was implemented by inserting fiber optic sensors into slope and subgrade models in order to verify the feasibility of application. The research results shows that FOS technology can satisfy the needs for acquiring information to reflect safety condition of operation from high-speed railway infrastructures due to its characteristics of real-time, remote, on- line, and continuous behaviors. Furthermore, the safety monitoring technology based on FOg is feasi- ble for assessing safety condition of high-speed railway ods are integrated into application software system. infrastructures if evaluation and analysis meth-
