针对路基沉降变形监测工程中存在的耗费大量人力，无法实时掌握路况信息的问题，研制开发了温度不敏感型尤纤光栅沉降位移传感器，其量程达到100mm，测量精度0．1mm。对两个多月的现场试验数据分析表明，光纤沉降位移传感器实时反映了路基面的沉降状况，尤其对降水等因素引起的路基面沉降速率的变化能够及时准确的响应。

We develop a temperature-unaware fiber Bragg grating （FBG） displacement sensor in view of big labor-consumption in the monitoring of railway roadbed deformation and no acquisition of real-time road information. It has the measurement range of 100 mm and measurement accuracy of 0. 1 mm. Data analysis of more than two months scene test shows that the designed sensor can reflect the real-time information of the railway roadbed deformation, especially for the information of the negative influence of precipitation on the rate of roadbed deformation.
