A laboratory study of the soil around injection-expanded wells: physical and mechanical characteristics changes

Ihnatov Siergey V.

Vol. 11

The article is devoted to the description of the physical processes occurring in the soil when cement mortar is injected into the ground under pressure. The paper determines the reason for the lack of knowledge of such kinds of changes in the soil’s physical and mechanical properties around a well expanded by the injection. The article presents the author’s own results in the variability of the physical and mechanical properties of the soil during ground hardening by the injection, in time and in orientation. The differences over time in sand and clay characteristics are also presented.
