Methods of experimental study of the stressed state of rock massifs and reinforced concrete elements of the support
Abstract
At the Department of Construction of Mining Enterprises LGI developed a method of stress measurement, instruments and apparatus, which are 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 mountain massif, providing it with a good enough contact with the walls of the borehole, then as a result of the movement of the walls of the borehole under the action of the load, the sensor readings will simultaneously change. The forces acting on the sensor will decrease or increase depending on the location of the rock mass under compressive or tensile stresses.
