Compared with the traditional physical model test

centrifugal test can simulate the long term process of soil freezing with full-scale stress in a short time. However

there are few researches on the centrifuge modeling of cold regions engineering. At present

scaling laws and similarity conditions of thermal dynamics of freezing soil in geotechnical centrifugal modeling are still not completed

which has become an uncertain factor in quantitative analysis of frost heave by centrifugal technique. Based on hydro-thermal-mechanical interaction process in saturated freezing soil

dimensionless variables have been established by Butterfield dimensional analysis method. The scale factors of the pore pressure

thermal diffusion

pore water migration

consolidation of freezing soil in centrifugal modeling have been derived. In centrifugal test

the effect of water migration

thawing soil consolidation and heat diffusion have the unified time factor 1/N2 of the prototype model

and the scale of velocity of unfrozen water is N above the prototype model. In addition

an application of centrifugal modeling of frozen-thawing process about canals has been carried out by cold regions engineering centrifugal modelling facility.
