三峡库区重庆市巫山县移民新城地质灾害GPS监测网建设

GPS Network Construction for Geologic Disasters Monitoring in the Newly Migrated Wushan County, Chongqing City, Three-Gorges Reservoir Area

一、前言与三峡工程相联系的库区城镇迁址移民是一项大规模的人类活动,这一活动将对库区周边地质环境体系产生影响和作用,为此,对于区域地壳稳定性,水库诱发地震和预计会发生的其他地质灾害均需进行研究。本文介绍了在巫山县移民新城区建设的GPS卫星定位监测网及流动地倾斜监测网。其目的是对高边坡、高挡墙,以及滑坡体的稳定性开展监测和研究。

The GPS monitoring network construction in the newly migrated Wushan County,Chongqing City,in Three-Gorges Area is introduced in present paper.The purpose of the network is to monitor and study the stability of the high side slope and high water barrier,to grip their dynamic process and failure mechanism,and to establish hazard prevention methods.The reservoir water level will rise considerably after the Three-Gorges Dam is built and that might cause a series of geologic hazards.The network is to assure early detection of slope deformation and landslide migration,as a result to decrease possible loss mostly in geological hazards.
