About of the application of electroosmosis in protecting against underflooding of land

Considered of the projections and modeling methodology electroosmotic filtering groundwater in soils in the protection against underflooding in urban construction and agriculture. The aim of the study is to provide a staged tasks in the form of initial differential equations of motion of the joint process of water and electricity supplies. Scientific novelty of the article is contained in the statement of filtration of groundwater under the combined influence of pressure gradients and electroosmosis. Based on phenomenological laws electroosmosis and Darcy introduced practically important assumptions and limits of their applicability. This made binding theory to practice hydrogeological work in conditions of flooded land. For example, laboratory determination of soil electroosmotic fluid loss during the engineering survey found electroosmotic coefficient of soil water loss, which was received at the bottom shield driving Omsk 1 line subway. This example showed that the soil water loss when subjected to a direct electric current increases almost five times as a result of the effect of electroosmosis. This important point must always be borne in mind when there is a need to improve the effectiveness of protection against underflooding, especially in the non-stationary filtration. In the study conducted with the theoretical calculations on the example of the city of Omsk. Nonstationary electroosmotic filtering groundwater in the soil base. Electro-dewatering is recommended to combine with all-kuumirovaniem soil. When applying the fields of gravitational pressures and constant electric current occurs in the wet ground with a total rate of filtration. Formulated necessary for the practice of differential equations of gravitational electroosmotic filtration. Staged solved the problem in the form of initial differential equations of motion of the joint process of water and electricity supplies.
