Estimation of strength of horizontal excavations sides by condition of detachment of rock mass near the contour zones
Authors:
Abstract
It is known that the rocks in the sides of horizontal excavations are destroyed either by shearing on one or another sliding surface or by tearing off the near-contour zones of the massif on vertical surfaces. Fracture by shear is well explained from the position of the theory of limit equilibrium of a cohesive bulk medium. The second possible type of fracture - detachment of contour zones has no clear explanation.
