Abstract: The problem of dry soil wetting in case of a breakthrough of a pressure pipeline is considered. The importance of such a problem in terms of the danger of landslides of soil slopes is substantiated. In the region of full saturation, the possibility of the variations of the soil porosity due to chemical and mechanical suffusion and non-isothermal conditions is taken into account. Consideration of the pressure regime of filtration required the elucidation of the kinematic condition of the movement of the wetting front. The mathematical model is formed determining the directions of further research. |
Keywords and phrases: filtration, man-made accident, heat and mass transfer, suffusion, kinematic condition. |
