Abstract
Method of normal load prediction on vertical shaft lining which is constructed in nonlinear rock mass is suggested. It is supposed, that limit state zone is formed around excavation. The deformation properties of rock mass in the suggested method are determined according to nonlinear rock model. In order to predict stress and strain state around excavation the equations of deformation plasticity theory are used. The Mohr-Coulomb strength criteria is taken as a yield surface.
