The paper presents an analysis of the results of tests carried out on loess subsoil in the Lublin region, classifi ed geotechnically according to PN-86/B-02480:1986 and PN-EN ISO 14688-1:2006 as silt, sandy silt and silty sands. In the field, over 300 CPT/CPTU with electric and mechanical cones tests were performed, testing a total of about 2,700 lm of the loess profile. In several places, comparative tests of the probing resistances obtained with different cones were carried out. In selected places, holes were drilled directly at the penetrometer tests and samples were taken for the laboratory tests. Moisture, consistency limits were determined in the laboratory. In addition, the strength parameters (angle of internal friction and cohesion) and deformation parameters (oedometer modules) were analyzed. The obtained results were also compared with the literature data and the results of tests carried out commercially for design purposes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
