The Division of Building Research, National Research Council of Canada (DBR, NRCC) has been engaged in field and laboratory studies of the effects of swelling and shrinking clay soils on foundations of various structures for more than 25 years. The influences of natural climate and vegetation, and of man's landscaping, building construction and maintenance activities on the behavior of deep deposits of highly expansive clay soils in western Canada have been investigated. Measurements of ground movements, soil moisture content and temperature changes extending over periods as long as 20 years have demonstrated the complexities of subsoil responses in natural and disturbed environments associated with urban development.Depuis plus de 25 ans, ...
