Methods of experimental study of the stress state of rock masses and reinforced concrete support elements
Abstract
At the Department of Construction of Mining Enterprises of LGI a method of stress measurement, instruments and equipment was developed, which is characterized by simplicity, reliability and sufficient accuracy. The method is based on the assumption that if a sensor is placed in a borehole in a rock mass, providing it with sufficiently good contact with the borehole walls, then as a result of displacement of the borehole walls under load, the sensor readings will change simultaneously. The forces acting on the sensor will decrease or increase depending on whether the rock mass is subjected to compressive or tensile stresses.
