Abstract
A new variational statement represented in the form of computational algori thm is proposed for elliptic systems of equations, which describe the behav ior of structurally inhomogeneous geomedia under static loads. The inverse problem of boundary condition determination and calculated domain orientati on from the point data of strain measurement is solved, which makes it poss ible to simulate adequately the stress-strain state of a rock mass.
