摘　　要：钻孔倾斜仪是一种测定钻孔深部位移的原位监测仪器，通过监测可以确定岩（土）体内滑面的位置、位移量和滑动方向，对分析边坡稳定性、确定滑坡动态起着重要的作用。为确保人民生命财产安全及水库的安全运营，应用CX-03系列测斜仪对高台滑坡的深部位移进行了监测分析，该滑坡GT1测孔未出现位移突变，GT2在11～16m处推测可能存在滑带，两测孔的累积位移量都较小，判断目前该滑坡仍处于较稳定状态。Borehole inclinometer is a monitoring instrument in situ to measure lateral displacement of borehole. The slip crack position, size and glide direction in rock and soil can be determined by measuring. It is important in analyzing the stability of side slope and ascertaining the developments of coast. In order to guarantee people＇s lives and property safety, and warrant the safely work of reservoir, CX-03 inclinometer is used in analyzing the project example-Gaotai Slope. The measured hole GT1 did not appear displacement mutation, measured hole GT2 maybe exist slip band, and the total displacements at hole GT1 and GT2 are very small, so the slop is at steady state at present.
