分布式光纤传感网络在边坡变形监测中的应用

The application of distributed optical fiber sensing net in slope monitoring

介绍了测量边坡变形的新方法——分布式光纤传感监测技术,具体叙述了线型分布式光纤传感器、螺旋型分布式光纤传感器和BOTDR光纤传感网络的传感机理及埋设工艺,利用这3种方法对边坡变形进行监测,可以及时掌握边坡的安全稳定状态信息。

A newly developed fiber optic sensing net applied in slope monitoring is presented in this paper. The sensing mechanism and inbuilt technique of linear distributional optical fiber sensor, spiral distributional optical fiber sensor and BOTDR optical fiber sensing net are discussed, and the information of slope stability can be obtained.
