GPS技术在震后地质灾害监测中的应用
|
摘要
本文通过在地震灾区布设GPS地表位移监测网监测不稳定斜坡地表位移项目,阐述了在震后特殊情况条件下进行GPS地质灾害地表位移监测中监测点位选择、监测网布设、数据处理的方法。监测结果表明,GPS地质灾害地表位移监测的精度达到毫米级,完全可以应用于震后重大地质灾害应急勘查。
In this paper,by GPS surface monitoring network project in the earthquake area to monitoring the unstable slopes of surface displacement,described the GPS monitoring of geological disasters in surface displacement monitoring sites selection,laid monitoring network,data processing method in the special circumstances after the earthquake.Monitoring results show that,GPS surface displacement monitoring of geological disasters in the accuracy of the millimeter range,can be fully applied emergency post-earthquake survey of major geological disasters.
