摘　　要：自动实时的边坡危岩变形失稳监测是预测滑坡等地质灾害发生的有效手段,有助于掌握其规律,及时分析并作出安全量性评价,使边坡灾害的概率及损失减到最小,甚至避免发生.为此,采用ZigBee无线传感器网络技术对边坡危岩的倾角和水位信息变化进行实时采样监测,通过无线通信和网络传输进行远程信息交互,实现滑坡等地质灾害的监测和预警.对该监测系统结构体系、无线传感器网络拓扑结构、无线传感节点的结构和软硬件设计、系统的性能和应用情况等方面进行了设计与测试.相比传统的岩土工程灾害监测系统,优点有实时监测及维护简便、系统成本低、节点简单及易布设、监控区域展扩方便等.The automatic and real-time monitoring of the deformation and instability of the slopes and crags is an effective means to predict the landslide and other geological disas-ters. It helps people grasp the rules of those disasters,makes a qualitative or quantitative safety evaluation in time,and thus minimizes the occurrence probability of the geological disaster of landslide and damage caused by the disaster. Therefore,the rake of slopes and crags and the change of water level is sampled to real-time monitor by the means of ZigBee WSN technology in this essay. And teleprocessing interaction is made through wireless＂nbsp;communication and Internet messaging so as to monitor and early warn the landslide and other geological disasters. The structure configuration of this monitoring system,the topolo-gy of WSN,the structure and design of hardware and software of the nodes of wireless sen-sor,and the function and application of the system are introduced and discussed. Compared with the traditional monitoring system of geotechnical disasters, it has the advantages of simple nodes distribution,reliable system,easy maintenance,easy expanding of monitoring scale and low cost and so on.
