Justification and selection of the method of control over the frozen soil structure preservation when working out the drilling parameters of engineering-geological wells.
Abstract
For engineering geology it is very important to take samples of soil with undisturbed structure. Especially difficult in this respect is the sampling of monoliths from frozen soils in the process of borehole sinking. In order to work out the technology of drilling wells in frozen soils, experiments were set up, in the course of which the main difficulty was the choice of the method of control over the state of structure preservation in the process of drilling ...
