Abstract
Roughness of the main crack surface is an assessment criterion for stress state of geomaterials for the quantitative connection has been found between the crack roughness and stress state of geomaterials. Roughness reduces with an increase in the maximum normal stresses in the zone of failure (the area of the maximum shear stresses). Based on this regularity, the method has been developed to assess stresses using the crack surface roughness in geomaterials.
