CERTAIN ASPECTS OF ENGINEERING GEOLOGY IN PERMAFROST

PERMAFROST DISTRIBUTION REACHES ONE-FIFTH OF THE DRY LAND SURFACE OF THE WORLD AND THE NEED FOR MORE KNOWLEDGE ON IT IS DERIVED FROM THE NECESSITY OF OPENING NEW FRONTIER AREAS. THE OCCURRENCE IS COMPLEX AND IS CONNECTED WITH MANY PHENOMENA NOT FOUND IN OTHER PARTS OF THE WORLD. PATTERNED GROUND, ICE WEDGES, PINGOES AND ICINGS ARE DESCRIBED IN GENERAL TERMS. THE MECHANICAL PROPERTIES OF SOIL IMPROVE DRASTICALLY BY FREEZING. STRENGTH OF FROZEN GROUND IS DISCUSSED. SINCE FROZEN GROUND IS CLOSE TO ITS MELTING POINT AND DISPLAYS CREEP, ITS RHEOLOGY IS DISCUSSED. FOUNDATION CONSTRUCTION, ROADS, HIGHWAYS AND AIRFIELDS COULD NOT BE SUCCESSFUL WITHOUT THE ENIGINEERING GEOLOGIST. EXCAVATION TUNNELING AND MINING ARE DIFFERENT IN PERMAFROST THAN ELSEWHERE. THE THERMAL REGIME OF ARTIFICIAL SUBSURFACE OPENINGS MAY BE REGULATED SUCCESSFULLY AND INEXPENSIVELY. BESIDES PERMAFROST, THERE IS ARTIFICIAL FROST. FREEZING GROUND BY ARTIFICIAL MEANS HAS COLOSSAL ADVANTAGES AND IS WIDELY USED. PRINCIPAL TOPICS IN ENGINEERING GEOLOGY IN PERMAFROST ARE REVIEWED. MECHANISMS, FORCES AND ENERGIES ARE EMPHASIZED. /RRL/A/
