摘　　要：滑坡是人类面临的主要地质灾害之一,而滑坡监测是减少滑坡灾害的有效方法之一,其中外观监测具有能监测滑坡体的运动特征等优势,在滑坡监测系统中占据了重要的地位。从滑坡监测控制网布设、监测点布置以及观测频率和周期的确定3个方面,结合滑坡的等级、变形阶段、滑坡类型以及变形特征等方面进行针对性布设实施,使其滑坡监测不仅经济合理且同时能较好地反映滑坡变形趋势,为后期预测预报分析提供可靠数据支撑。Landslide is the one of the major geological disaster of human face,but the landslide monitoring is an effective method to reduce the landslide hazard,and the external monitoring which occupy the important position in the landslide monitoring,has advantage to monitor the movement of landslide features.This paper discussed from three aspects:the laid of control network,the layout of measuring points and accuracy and frequency,combined with the decline of the level,the deformation stage,the deformation characteristics of landslide types,laid in the implementation of targeted and so on,which have been laid to implement targeted,in order to achieve economic rationality and landslide monitoring to better reflect the same trend of landslide deformation and Provide reliable data to support the latter prediction analysis.
