The interaction between a flighted steel pipe pile and frozen sand
Foundation construction in permafrost regions often make use of "thermopiles" or thermal piles to maintain the permafrost and to transfer load to the soil. Often "thermopiles" are constructed using shafts with continuous helical flighting attached to increase bearing capacity. Th...
