Abstract

The calculation theories and analysis methods of thermodynamic stability of embankment engineering in cold regions are systematically summarized. The engineering theories and methods taken to control frost heave and thaw settlement in seasonal frozen soil regions may not be applicable in permafrost regions. The active cooling technology of roadbed should be utilized to limit the effects caused by both climate changes and human engineering activities. The paper mainly discussed the calculation theories and analysis methods of four kinds of embankment structures, i.e., the crushed-rock embankment, duct-ventilated embankment, thermosyphon embankment, and composite embankment. It is expected that a scientific basis could be provided for the theory, design, and application of embankment constructions in cold regions.
