Stress-Strain State of Weightless Inhomogeneous Array with Cylindrical Hole

Abstract:

When creating underground pipelines, tunnels and other long cylindrical holes often used drilling-and-blasting method of penetration. Depending on the type of rock in the array may be local induration or sintering which results in increase in the deformation properties of the ground, or cracking resulting in a decrease in deformation properties. Thus the array becomes inhomogeneous. The article provides a calculation of the stress-strain state of array considering its local inhomogeneity.
