Аннотация:The static loading of a solid, porous, gas- or liquid-saturated medium is examined. The equations of state of each components of the porous body are assumed to be known, The dependences of the average pressures in the components as functions of the porosity and average density are obtained. Numerical calculations of loading diagrams for porous media are made. This dependence is shown to be irreversivle in nature, the initial pressure of the gas-saturated medium noticably affecting the final porosity.
