摘要：
Mathematical models of the stress-strain state of the rock mass and lining during the construction of underground structures are considered. It is noted that elastic rocks are rocks in which the deformation process under the action of external forces is reversible, i.e. the energy due to the work of external forces is not absorbed. Equations of motion and equilibrium are given under conditions of elastic deformation. It is recommended to use the finite element method for modeling the stress-strain state of a rock mass and lining for solving the equations of motion and equilibrium in conditions of elastic deformation.
