PENETRATION OF FROST INTO THE SOIL, WITH SPECIAL EMPHASIS ON THE SCOPE FOR PREVENTING DAMAGE DUE TO FROST HEAVE

ONE OF THE PROBLEMS OF MAJOR ECONOMIC IMPORTANCE IN BUILDING TECHNOLOGY IS THAT OF PREVENTING DAMAGE DUE TO FROST HEAVE IN THE SOIL. THIS APPLIES IN PARTICULAR TO ROADS AND RAILWAYS, FOR WHICH THE ANNUAL REPAIR AND MAINTENANCE COSTS AMOUNT IN SWEDEN TO SEVERAL MILLION KRONOR. IT IS ALSO A MAJOR SAFETY PROBLEM IN THE CASE OF THE RAILWAYS. WITH VERY FEW EXCEPTIONS, THE FOUNDATIONS OF BUILDINGS MUST BE TAKEN DOWN TO A DEPTH NOT REACHED BY FROST PENETRATING INTO THE SOIL, PROVIDED OF COURSE THAT THE PROPERTIES OF THE GROUND ARE NOT SUCH THAT THE POSSIBILITY OF THE PENETRATION OF FROST IS EXCLUDED. THE MECHANICS OF FREEZING OF THE SOIL AND ITS CAUSES ARE NOW KNOWN THANKS TO EXTENSIVE RESEARCH, MAINLY IN COUNTRIES WITH A COLD OR ARCTIC CLIMATE. LITERATURE ON THE SUBJECT IS SO VAST THAT THE BIBLIOGRAPHY ACCOMPANYING THE PUBLICATION SUMMARIZED HERE CANNOT COME ANYWHERE NEAR TO MENTIONING ALL THE WORKS PUBLISHED ON THE SUBJECT. THE PURPOSE OF THE REPORT IS TO PROVIDE A REVIEW OF THE RESULTS ACHIEVED TO DATE SO THAT DESIGN ENGINEERS ACTIVE IN THE FIELD CAN OBTAIN AN ORIENTATION ON BOTH THE THEORETICAL AND APPLIED ASPECTS OF THE PROBLEM. /AUTHOR/
