Abstract
Test results show that the settlement process of model piles is mainly the rheological process of fmzen soil under shear loading. The settlement rate of model piles increases with increasing temperature of frozen soil, decreasing royghness of pile surface and increasing rigidity of pile foundation. As the water content of frozen soil reaches its saturation value, the settlemerrt rate is the least. When the level of loading is higher, the settlement rate under dynamic loading is less than that under static loading. With the level of loading lowering, the effect between dynamic and static loading on the settlement rate becomes close gradually. Under the present test conditions, the settlement rate of model piles is independent of the frequency of dynamic loads.
