Mathematical Modeling of Deformation of Self-stress Rock Mass Surrounding a Tunnel
The mathematical model of structurally inhomogeneous rock mass, describing the property of rocks to accumulate and release elastic energy is used in the study. The finite element algorithm and programs for solving plane boundary-value problems are developed. The authors solve a problem on deformation of rock mass with a disjunction. It is shown that driving of horizontal tunnel nearby the disjunction can provoke the accumulated elastic energy release, which affects stress state of rock mass around the tunnel.
