The article presents the results of field tests of driven piles on collapsible soils of Type I, conducted at the construction site of the repair and mechanical workshop of a plant under construction. The purpose of the tests was to determine the bearing capacity of driven piles under vertical static compressive load in conditions of collapsible soils. The static tests were performed in accordance with the requirements of GOST 5686-2012. Prior to loading, the foundation was pre-soaked to a depth of 3.8 m to achieve saturation of the collapsible soil. Within the framework of the study, laboratory tests of samples were carried out to determine their physico-mechanical characteristics, and graphs of settlement versus load and time were constructed. The test results showed that driven piles of the С120.30-13 grade demonstrated high bearing capacity (up to 1083 kN) with minimal settlements (up to 4.7 mm), confirming their effectiveness for construction under complex engineering and geological conditions.
