Effect of bearing pressure on the strength of a rock mass containing cylindrical cuts

The three-dimensional problem of stress distribution in a rock mass in the vicinity of two cylindrical holes located in the zone of elevated mountain pressure is solved using the boundary-element method. The technogenic disturbance of the mass with regular strength anisotropy was estimated quantitat...

Beschreibung
Zusammenfassung:	The three-dimensional problem of stress distribution in a rock mass in the vicinity of two cylindrical holes located in the zone of elevated mountain pressure is solved using the boundary-element method. The technogenic disturbance of the mass with regular strength anisotropy was estimated quantitatively using specially introduced parameters.
