Ground State and Determination of the Strength and Compressibility Characteristics of Plastic Frozen Soils with the help of the Static Probing Method

摘要

Determination of the ground state and of the strength and compressibility characteristics of plastic frozen grounds is one of the principal issues being solved in the course of engineering and geocryological research. Traditionally it is solved as a result of: drilling of engineering and geological boreholes, selection of monoliths, their transportation (usually over long distances) to the sites of geocryologic laboratories equipped with refrigerating chambers and with the necessary facilities for laboratory testing of grounds. The research carried out by foreign experts and the experts of our country (including NIIOSP) showed that it is possible to determine the properties of these grounds even in conditions of their natural occurrence by using the static probing method. Using probing in combination with traditional methods of geo-technical site investigations carried out in lower volumes allows us to considerably reduce their overall duration, cost and labor intensity.
