【 摘 要 】

Numerical and analytical studies provided data on the interaction of screw metal piles of various constructive solutions (single-blade, double-blade) with clay soil foundation. The results of the research made it possible to develop a method for calculating the final settlement of single screw double-blade piles for foundations of lightly loaded prefabricated buildings. The method is based on patented design solution for a screw double-blade pile and takes into account the non-linear dependence of its settlement with the applied external load. The scope of the method application under consideration extends to screw double-blade piles up to 3.0 m in clay soils, mainly from soft to semi-solid consistency.
