FROST HEAVING FORCES IN SOILS

Basic information is presented related to the complex research that has been performed on the interaction of frost-heaving soils with engineering structures. The evaluation of the soil-foundation interaction gave consideration to the site conditions, such as the thickness of the seasonally frozen soil layer and its physical characteristics, depth of the ground water level, the climatic factors, the foundation type (dimensions, surface roughness and construction material), as well as the thermal regime of the foundation. The total out-heaving force was systematically measured with simultaneously operated devices. The results demonstrate the great range that exists for the numerical values of the specific out-heaving force even when measured within a restricted experimental area. This is the result of the dependence of that force as well as other parameters characterizing frost heaving and its interaction with foundations, on a number of environmental factors like climate, soil, hydrogeology as well as the upward mobility of the foundation and the roughness of the lateral forces. It is asserted that the numerical values of the out-heaving force measured in the field cannot be single-valued. Their probability varies within certain limits. Hence, such values of the out-heaving force obtained from short term tests and one-time measurements are chance values. Such data may be utilized for setting design values provided that the limits of probable variation of values are set up.
