Distribution Stresses in Elastic Porous Saturated Half-Space Under Axial-Symmetric Normal Loading

Abstract

Analytical solution is constructed for problem definition stress-strain state in porous saturated half-space for situation of action on penetrable half-space boundary by pressure is distributed on circle region. Inter-influence of two phases is considered: stress state of rigid skeleton to put pressure on liquid/gas and on the other hand the pressure in a liquid/gas phase represents a source of additional stresses in a rigid deformable skeleton. Using the algorithms are developed in the previous works of authors it is possible to construct the solution in general case of loading actions. On the basis of the constructed solution it is possible to building up algorithms of the solution for various classes of important applied problems of geomechanics.
