钻孔测斜仪是一种测定钻孔深部水平位移的原位监测仪器,在边坡工程原位监测中应用最为广泛。通过监测可以确定岩(土)体内滑裂面的位置、大小和滑动方向,对分析滑坡稳定性、确定滑坡动态起着重要的作用。本文介绍了钻孔测斜仪的组成、工作原理、测斜管的理设技术和监测技术,并应用钻孔测斜仪对工程实例进行研究分析。
Drilling inclinometer is a kind of in situ monitoring instrument for measuring horizontal displacement of deep borehole. It is the most widely used in situ monitoring of slope engineering. Through monitoring, the location, size and sliding direction of the slip surface can be determined, which plays an important role in analyzing the stability of the landslide and in determining the landslide dynamics. This paper introduces the composition and working principle of borehole inclinometer, the rationale and monitoring technology of inclinometer pipe, and analyzes and analyzes the engineering examples by using borehole inclinometer.
