摘　　要：利用光纤传感技术，提出了一种新的滑坡监测方法，即采用微弯机制的强度调制光时域反射技术，对边坡变形进行全分布式传感监测.Using the technology of optical fiber sensing,a new method for monitoring slope slide is proposed,i.e.,to use the intensity modulating optical and timing reflecting technology of microbend mechanism to carry out the whole distributed sensing mornitoring of the slope The method has been realized successfully in Geheyan hydropower plant at Qingjiang River.
