| 中文摘要: |
| 基于光纤布拉格光栅(FBG)传感器技术,针对边 坡开挖过程滑坡监测问题,通过在边坡布 设的多个传感器组成的监测系统,测得实验过程中传感器表面应变的变化规律,实现 对滑坡体内部 位移的监测；运用K值标准差准则,将边坡失稳滑动规律定量化。实验结 果表明,钢筋应变传感器测量 的滑坡体内部位移变化与理论分析一致,表明钢筋传感器可实现对滑坡的准确监测；通过内 部位移的微小变化的监测,可实现对边坡失稳进行预警。 |
| 英文摘要: |
| Based on experiment and monitor principles of fiber Bragg grating (FBG) sensor,this paper focuses on monitoring the landslide under excavation and gains the surface stress change principles of the sensor.The sensing system contains many sensors set up along the slope,thus the monitoring of the internal stress of land slide can be realized.Using the standard deviation criterion of K value,the sliding law of the sl ope instability can be quantified.The experimental results show that the internal displacement changes monitored by th e FBG are consistent with the theoretical results,demonstrating that FBG can be us ed to accurately monitor the landslide and warn the slope instability by monitoring the micro changes of internal displacement. |
