Abstract

The article deals with application results of the first national measurement system with deep-water three-axis tilt sensors (DTT) based on micromechanical accelerometers (MMA) in the solution of highlands geotechnical monitoring on Olympic speedway Adler - Krasnaya Polyana. It is shown that this system provides on-line monitoring of horizontal displacement array of the ground during a long period of time, thereby providing the timely warning of possible adverse situations during construction and operation. The achieved accuracy level equal to a few millimeters and relatively low cost makes this system more attractive, especially in the continuous monitoring organization of lengthy geological objects.
