Regularities of soil filtration coefficient changes on the application of ground injection technology

Abstract

The paper analyzes the anti-contagious shield research results provided by regression models, implemented in the «Compex» software. The analytical and graphical dependences of soil filtration coefficient from the following factors are identified: the duration of mortar supply, by which a shield is formed, bentonite powder concentration per unit of volume of hardening mortar and the discharge pressure (supply) of this mortar in the base soil.
