摘要： 基于光纤故障定位技术提出了一种边坡安全自动监测预警系统，简要介绍了其系统组成与结构、目标与功能、以及软硬件设计与实现等。这种边坡监测预警技术改变了以往的分散式监测为分布式监测，具有布设灵活、成本低廉、操作简单、直观可靠和便于实时远程监测等优点，突破了以往监测预警手段只能对重点边坡的重要部位布控的局限，特别适用于对高等级道路的大量边坡工程实施全面安全管控，是边坡安全监测预警技术的一个崭新的研究和发展方向。

Abstract: This paper presents the design and implementation of an automatic monitoring and alarming system for the slope stability based on the fiber optical fault locating theory. The system components and their structures, functions, targets and software as well as hardware design and fabrications are introduced in the paper. The new device monitors the target slope with a systematically distributed monitoring points. It has the advantages of flexible monitoring points, low cost, easy to operate, reliable monitoring results and suitable for the remote monitoring. This device has also the advantage over the conventional monitoring device that can only monitoring several important local points and therefore is suitable for the higher grade roadway slopes with large monitoring points.\=
