Abstract. The article is devoted to the development of a method for determining the torque required to install screw piles. The relevance of this work stems from the use of screw piles in transportation construction and the need to make a rational selection of installation equipment. Existing analytical methods, primarily developed for single‑blade piles, do not always provide sufficient accuracy due to variations in soil conditions and the lack of consideration for local features of the geological profile. The proposed approach is based on the correlation between the torque and the ultimate bearing capacity of the pile. A calculation method is proposed for estimating how the torque changes with depth, using data from static cone penetration testing. To verify the method, full‑scale studies of screw piles were carried out at a test site. During the installation process, torque measurements were taken. Static cone penetration testing was carried out near the piles under study. After installation the test piles, their static tests were performed. A comparison of theoretical and experimental torque values with depth showed good agreement, which confirms the reliability of the proposed method. The developed approach makes it possible to determine the torque not only at the design elevation for installing a screw pile, but also along the entire depth of penetration. Using static cone penetration testing as a cost‑effective and efficient method for soil investigation enables a larger number of measurements to be taken and allows machinery of varying power ratings to be selected on a well‑founded basis. Dividing the construction site into zones makes it possible to optimise technological solutions for installation screw piles. This helps improve work productivity and reduce financial costs during construction.
