The study of a new construction of a micropile are presented. The proposed vertical micropiles of a new construction has a large surface area due to the spiral shape and a bigger bearing capacity compared to the usual micropile. As a result, numerical modeling, the influence of the number of a pile spiral turn and the relative “elongation” of a spiral turn on the change in load capacity, as well as the features of its compressibility. Analysis of the results of the numerical modeling shows area of the effective constructive combinations of the spiral turns number along the length of pile and the “elongation” (width) of the turn. This area arranges the biggest load capacity of the spiral pile compared to the usual micropile. Additionally, restrictions on compressibility have been imposed to confine torsional tensions. At conclusion, the authors for-mulate the problems for continuation research.
