丹巴县甲居滑坡GPS地表监测阶段成果

The phase results of the surface landslide monitoring with GPS in Jiaju, Danba county

本文主要介绍GPS用于地质灾害滑坡地表监测的技术和方法,并通过在四川丹巴县甲居滑坡区布设的GPS监测网的测量,阐述了在GPS滑坡监测时,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滑坡监测的精度达到毫米级,完全满足滑坡监测的精度要求.

A surveying method for landslide monitoring using GPS is introduced. Through the experiment of landslide monitoring with GPS in jiaju, danba County, Sichuan Province, the authors elucidate the selection of the sites of monitoring stations, lay-out of the monitoring baseline network and method of GPS data processing when GPS monitoring of a landslide is conducted. The results of the experiment show that landslide monitoring by GPS can reach an accuracy of mm scale and fully meet the demands of landslide monitoring.
