Methods of Research on Frost Heave of Soil and Foundation - Freezing Soil Bulk Interaction in Terms of Seasonal Deep Frost Penetration including Areas of Pressure Migration

摘要

Based on long-term research on soil frost heave conducted in laboratory and in situ including both experimental and expert investigation sites the influence of groundwater level on frost heave-induced deformations has been identified. Nature of change of moisture during frost penetration has been studied, parameters of changes of water accumulation coefficient for the main types of soil in Minusinsk cavity have been obtained. Options of anti-heave activities during construction for driven and end-bearing piles have been proposed.
