摘　　要：以京津冀协同发展交通网络地质安全监测预警系统项目为背景,选取北京市房山区G108国道王家台不稳定斜坡及堂上村泥石流两个典型区域,通过布设GNSS设备监测地表位移情况,阐述了GNSS地表位移监测的点位选择及埋设、监测网的布设、数据处理等内容。对2019年4-7月GNSS监测数据的结果进行对比分析,其地表位移发生一定变化且在一定范围内波动,但相对稳定,可作为地质灾害安全监测预警的数据依据。Based on the coordinated development of Beijing-Tianjin-Hebei traffic network safety monitoring and early warning system project as the background,select the Beijing Fangshan district G108 national Wangjiatai hall of unstable slope and village landslide area,two typical of GNSS equipment arranged by monitoring the surface displacement,this paper expounds the GNSS surface displacement monitoring point selection and bury,monitoring network layout,data processing,etc,in April to July,2019 by comparing the results of the GNSS monitoring data,it must change of surface displacement and fluctuate within a certain scope,but relatively stable,can be used as the data basis of safety monitoring and early warning of geological disasters.
