Singularities in the formulation of geomechanics boundary-value problems

Abstract

Certain questions on the formulation of boundary-value problems and the interpretation of computational results in investigations of the stress-strain state of a rock mass in the neighborhood of a system of drifts are considered within the framework of an elastic model, taking account of gravity, tectonic stresses, the shape of the earth's surface and qualitative estimates of the redistribution of the initial stress state in the neighborhood of the drifts. Elements emphasized are initial stress state, principal vector of the external forces, estimate of the forces acting in the neighborhood of the drift, the irregular structure of a rock mass, and computation methodology.
