Abstract
The paper presents the comparison of the laboratory results of the soil consistency with the results of static CPT tests. The study was carried out on the loess terrain in Lublin. The laboratory results were compared with the values estimated from the CPT tests based on the interpretation of various sources. The determination of an own interpretation formula was also undertaken. It was noticed that for the geotechnical division of the loess soil it is more accurate to use the qc value as the leading parameter, rather than the parameter as is the norm for cohesive soil. Given the possibility of obtaining more authoritative parameters determining the bearing capacity of the subsoil, the target is the recognition of the relation between the specified parameters.
