【摘要】 高切坡变形和失稳是三峡库区广泛分布的一种地质灾害形式,严重影响着移民房屋、道路交通以及人民生命财产的安全。本文以万州库区为例,介绍了高切坡变形监测网络构成。该网络采用了高精度的GPS空间定位技术,全站仪变形监测技术、数字化精密水准测量、先进的遥测台网技术并与地理信息系统相结合,构成了一个空间上点、线、面相结合的高效率高切坡变形监测网络系统。该变形监测系统2008年建成,到目前为止,已经获得了大量的宝贵的监测数据,为当地高切坡变形和失稳的预警预报提供了科学依据。更多还原

【Abstract】 As a kind of geological hazard,the deformation of high cutting slopes are widely distributed in Three Gorges Reservoir.This article takes wanzhou area for instances,the constitution of the deformation monitoring system of high cutting slope was introducted.This monitoring systems adoptes high precision geodetic technology,such as GPS,TPS,level measurement and remote monitoring network,combined with GIS and constructes consequently a geological disaster monitoring systems with great efficiency and power.Many kinds of slope deformation monitoring system are formed including a station,a survey line and a network spread out to a plane in space domain,to fullfill long,short and impending warning in time domain.This deformation monitoring network system has been built in 2008,and obtained a lot of valuable observation data and provided scientific warrant for precaution and forecast of the deformation of some high cutting slope.更多还原
