Teoria konsolidacji Biota ze zmiennym współczynnikiem przepuszczalności
AbstractEquations of Biot’s consolidation theory are generalized in the paper cutlet case, when permeability coefficient k can be treated as a function of the constituents of strain tensor The dependence equation given by Blot was taken in to consideration: kij-1 = bij = 2αeij + (b + βe) δij bij— elements of the coefficients of resistance of the fluid flow matrix α, β - constant coefficients b = 1/k , e = eii kij-1 - the inverse matrix of bij δij - Kroneoker’s symbol The ease of two media have been considered: compressible and incompressible /filled fully with incompressible fluid/ Darcy’s law adequately formulated, enables in this cas the estimation of α and β coefficients. The physical meaning of α and β is determined, and the method of their measurement is proposed. The equations of consolidation theory for the case existing fluid and skeleton sources are given vor variable medium permeability. Assuming the given relative potential the fluid filter displacement /Riot/, the method of the disco - Mime consolidation equations is presented. The problem of initial motions is also considered for the case when consolidative domain undergoes the action of the instant force.
