Local instability of horizontal tunnels of polygonal shape in viscoelastoplastic masses
The local instability of a horizontal mine tunnel with a regular polygonal cross section in a viscoelastoplastic rock mass is studied within the framework of the exact three-dimensional stability equations. The effect of rock-mass parameters on the critical pressure is estimated.
