METHOD FOR MEASUREMENT OF SMALL LINEAR DISPLACEMENTS OF LANDSLIDE PROTECTION WORKS

摘要

A method for measurement of small linear displacements of landslide protection works includes transformation of signal of vibratory acceleration to signal of vibratory displacement and filtration of those. One measures angular position of the vibration-measuring device, the signal of vibratory acceleration is corrected by value proportional to angular deflection of the plane of installation of vibration-measuring device from plane of horizon, additionally one carries out filtration of the signal of vibratory displacement in broad band of frequencies, the value of real linear displacement of the object is determined by constant component of vibration signal that is present after filtration.
