摘要
介绍了一种基于光纤应力传感的山体滑坡预警监测系统。阐述了分布式光纤应力传感原理与滑坡体内应力监测方法,设计了应力测量范围 0-15Mpa,空间分辨率 2m,测量距离 1km 的山体滑坡监测系统,并实验验证了监测方法的可行性。
A warning monitoring system for landslides based on fiber optic strain sensing is presented. The principle of quasi-distributed fiber optic strain sensing and the monitoring method for landslides with the internal strain of landslides are described. With strain measuring range 0-100Mpa, spatial resolutions of 2 meters, measuring distance 1km, the warning monitoring system is designed. The feasibility of the monitoring method is fully validated by experiment.
