A global function was defined, as well as partial functions, which predict shear strength modulus G0 values based on cone resistance for different soil groups with varying OCR values. The significance of the influence of the analyzed variables on the variability of the rigidity index (IR) was also examined. The analysis used the results of more than 100 static SCPTU and SDMT tests. Investigations were conducted in several locations in Poland, where the subsoil is constructed from soils of different geological origin. ER -
