摘要
根据光纤光栅传感的原理,提出了光纤光栅式封装应变传感器,对其传感特性进行了研究,并进行了室内实验。结合光栅传感监测滑坡的应用实例,探讨了光纤布拉格光栅传感元件在滑坡体上的布设工艺及监测过程。分析初期的监测结果,针对监测系统可能出现的问题提出了解决途径。
Based on the principle of Fiber Bragg Grating Sensor,the authors put forward packaging of fiber grating strain sensors,and studied its sensing characteristics with laboratory experiments. Fiber Bragg grating sensors in monitoring geological hazards were studied based on the emplacement of landslide processes and monitoring, and fiber Bragg grating sensors were used to monitor the process of change. In combination with practical applications, the field application examples of grating sensor for monitoring landslides were given. The early-stage monitoring results were obtained and analyzed. Advices are proposed for handling the problems that may occur during the instrumentation.
