基于多源数据山区地质灾害监测预警应用

Application of monitoring and early warning of geological hazards in mountainous areas based on multi-source data

本文结合北斗卫星导航系统(BDS)/全球卫星导航系统(GNSS)技术和物联网传感器技术,建立了地质灾害监测平台系统,利用监测数据对常见的泥石流、崩塌以及不稳定斜坡地质灾害进行了数据分析。研究结果表明,长时序监测下BDS/GNSS监测精度达到毫米级。实时监测精度达到2cm。结合多源数据分析建立地质灾害防治多维度指标的预警系统,并重点对缓变形地质灾害数据进行了分析,为地质灾害防治工作提供重要的参考。

In this paper,a geological hazard monitoring platform system was established based on BeiDou navigation satellite system(BDS)/global navigation satellite system(GNSS)technology and Internet of things sensor technology.The monitoring data were used to analyze the common geological disasters including debris flow,collapse,and unstable slope.The results show that the BDS/GNSS monitoring accuracy under long-time series monitoring reaches the millimeter level.The real-time monitoring accuracy reaches 2 cm.Combined with multi-source data analysis,an early warning system for multidimensional indicators of geological hazard prevention and control was established,and the data of geological hazards with slow deformation were analyzed,which provided an important reference for geological hazard prevention and control.
