APPLICATION OF ELASTICITY THEORY MODELS WITH STRUCTURAL PARAMETER FOR SOLVING ROCK MECHANICS PROBLEMS
The model of the linear elasticity theory with a structural parameter has been discussed. The system of constitutive relations in two-dimensional case has five independent equations while the classical theory has only three equations. Additional two equations are contained in the diffeomorphism postulate-suggestion of the smoothness of a displacement field. As a result of withdrawal of the diffeomorphism postulate, the structural parameter appears in the model. The problem on deformation of structurally inhomogeneous rock mass nearby tunnel is formulated and solved numerically. The influence of the structural parameter on the stress concentration in rock mass is assessed.
