Promising Screw Piles Designs for Construction on Permafrost Soils
Abstract Promising designs of screw piles with improved technical characteristics have been developed, which reduce risk of buckling from soil as a result of influence of tangential forces of frost heave, reduce energy consumption when screwing piles into the soil, and also simplify designs and manu...
