Engineering Method of Calculating the Settlement of Two-Bladed Screw Pile in Clayey Soil

A method is developed for calculating the settlement of single double-bladed metallic screw piles in clayey soils for the foundations of temporary buildings. The method is based on the use of a patented design of a screw double-bladed pile and takes account of the nonlinear load dependence of its settlement. It is established that for clayey soils with semi-solid consistency the discrepancy obtained between the experimental final settlements of double-bladed screw piles and the computational data obtained by the proposed method does not exceed 20-30%.
