Abstract	The international symposium on Ground freezing and frost action in soils was held from September 11 to 13, 2000, in Belgium. There were 6 main topics in the symposium: heat and mass transfer, frost susceptibility and frost heave, environmental soil freezing, engineering design, and case histories. Papers concerned with heat and mass transfer covered the physical parameters, the mechanism of the formation of natural gas and hydrate and pore ice, the theoretical model of heat and mass transfer and its application in engineering, etc. No clear breakthroughs were achieved in frost susceptibility and frost heave theory, but more emphasis was placed on applications, especially in the improvement of measurement methods, so as to get more extensive and accurate data. As to the mechanical properties of frozen soil, some enterprising attempts were made concerning its dynamic properties, the mechanical properties of deep frozen soil, and quantitative studies on the structure of frozen soil. In this paper, the main research achievements presented at the symposium are summarized.
