Abstract: The article is devoted to the difficulties encountered during construction due to difficult engineering-geological conditions in the territory of the Nizhnekamsk industrial hub, where the eluvial sandstones of the Urzhumian Stage are widely developed. Their structure and properties that distinguish them from ordinary sands and cause unpredictable behavior of the ground bases are analyzed. Lots of data from cone penetration tests, pile static load tests, and laboratory studies were collected and analyzed. Correlation dependencies between the physical-mechanical characteristics of the considered eluvial sandstones and the specific frontal resistance were established. Based on the systematization and analysis of field studies, regional dependencies between the parameters of cone penetration test and the strength and deformation characteristics of soils are constructed. The results are of great practical importance and make it possible to optimize the design and construction of infrastructure in a given area.

Keywords: weathering crust; eluvial sandstones; strength properties; deformation properties; cone penetration test; Nizhnekamsk industrial hub
