针对目前测斜仪存在的不足，利用光纤光栅传感技术的优势，研究开发了一种监测岩土体内部变形的光纤光栅测斜仪，并成功应用于某公路膨胀土边坡的坡体位移变形监测。工程现场边坡监测结果表明：该光纤光栅测斜仪监测的结果与常规测斜仪监测的结果比较吻合，验证了该光纤光栅测斜仪工作的可靠性。该测斜仪可和其它量测边坡参数的光纤光栅传感器组网成为一个监测系统，可实现对高边坡岩土体内部变形情况进行长期在线监测和安全预警预报。

Aiming at the deficiency of present inclinometer and using the advantages of FBG sens-ing technology,a fiber grating inclinometer which can monitor the internal deformation of rock and soil was developed,and it was successfully applied to monitor expansive soil slope displacement deformation of a highway.The site engineering monitoring results show that :the fiber Bragg grating inclinometer mo-nitoring results agree well with the conventional inclinometer monitoring results,manifesting that the work of the fiber grating inclinometer is reliability.The inclinometer and other fiber grating sensors can form a monitoring system.The monitoring system can achieve long-term online monitoring and safety early warn-ing to the high side slope.
