ABOUT FORMATION OF HYDRAULIC FRACTURES IN SOIL WHEN INJECTION OF CEMENT AND POLYMERIC SOLUTIONS FOR LIFTING AND STRAIGHTENING OF THE BASES
Abstract
The article considers the experience of formation of hydraulic fractures in the soil during injection of cement mortars and polymers with the formation of cracks in the vertical and horizontal directions. The formation of hydraulic fractures and their orientation in space is mainly affected by the stress state of the soil. When reviewing the available works on this topic no studies were found on the predicting of orientation in the space of the soil mass of hydraulic fractures. On an experimental site in Tula without loading on the surface and in large-scale odometers-barrels with load experimental works was carried on injection of cement mortar and geopolymer, respectively. The obtained "bodies" of hy- draulic fractures in soils were investigated and a technique of forecasting their orientation in space was proposed.
