Influence of deformation process of rock massif on the carrying capacity of rock bolts
The paper deals with the activation of rock bolts anchored in the rock massif at the rock bolt termination by the deformation process of the rock mantle of an underground opening of circular cross-section driven in the virgin hydrostatic stress field, i.e. with a centrically symetrical deformation. From the solution follows that the rock bolt activation by the deformation process of the rock massif depends on the depth of the opening under the surface, modulus of deformation, and Poissons number of the rock, length, and the building density of rock bolts, as well as on the initial deformation of the opening formed prior to the installing the rock bolts.
