中文摘要：
研究采用光纤传感技术实现对高速铁路轨道、路基、桥梁、隧道、边坡和涵洞等工务设施进行结构安全监测的可行性．将光纤传感器嵌入到边坡及路基结构模型中进行试验．研究表明，光纤传感技术具有实时、远程、在线和连续监测的功能特点，能够满足高速铁路工务设施结构安全信息采集的需要．基于光纤传感的安全监测技术，结合对监测信息分析评估的方法和软件系统，能够应用于高速铁路工务设施的安全状况评估．
英文摘要：
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-
