This paper presents a numerical simulation of the behavior of a cast-in-place steel pile filled with cement-sand grout under the conditions of permafrost soils in the Arctic. Physically based soil models (MO Granular and Cam-Clay) were employed within the ANSYS Workbench software suite. Both vertical and combined loading scenarios typical for pipeline supports were considered. Computational results were compared with field test data obtained in Yakutsk. A satisfactory qualitative agreement was demonstrated, confirming the adequacy of the proposed approach for the design and monitoring of pile foundations in permafrost regions.
