摘要：
It is proposed to assess the stress-strain state of a rock mass and its defects by measuring displacements of mine working contour. Algorithms and software to solve the elastic and elastic-plastic problems are worked out for a case when a working contour shifts to failure domain To compute of the working contour displacements, when all the shears except creep-strain occurred, the researchers set forth the process for continuous stress release in the contour of the preset geometry at continuous monitoring and recording of shear benchmark data at its boundary The process is demonstrated on shear measurements on a circular hole in a rubber plate under tension load.
