MOISTURE ELASTICITY OF THICK-WALLED INHOMOGENEOUS CYLINDER UNDER NONSTATIONARY HUMIDITY CONDITIONS

There is presented a solution of the problem of unsteady axisymmetric moisture transfer in a thick-walled tube, modeling part of ground mass, with the propagation of the moisture from the inner surface to periphery. At the second stage in mined the slow moisture transfer is solved quasistationary problem of moisture elasticity for heterogeneous body because of uneven changing the deformation characteristics of the soil by saturated it with moisture. The term "moisture elasticity" is used by analogy with the term thermoelasticity since the presence of moisture in the material induce forced deformations which is similar to the temperature deformations and problems of heat and mass transfer use the same mathematics.
