一、概述随着国民经济建设的发展,需要使用测斜仪的工程日益增多,例如水库土石坝工程,城市高层建筑基础地坑挖掘工程,露天矿床开采工程等等。所谓测斜,即土体岩基监测基准面相对原始位置的倾斜变形的测量。测量地球重力加速度矢量相对被测基准面之间的位置参数是测斜的基本原理,从悬吊重锤用肉眼瞄准直到目前最先进的力平衡伺服加速度计测斜仪都是基于这一原理。
I. Overview With the development of the national economy, there are an increasing number of projects that require the use of inclinometers, for example, earth-rock dam projects in reservoirs, foundation pit excavations in urban high-rise buildings and open-pit ore bed mining projects. The so-called incline, that is, the measurement of the slope deformation of the soil basement monitoring datum relative to the original position. Measuring the position of the Earth’s gravitational acceleration vector relative to the reference plane is the basic principle of the inclinometer. From the point of view of the pendulum with the naked eye until now the most advanced force-balanced servo accelerometer inclinometers are based on this principle.
