Interaction between mineral composition, water content and mechanical properties of saturated cohesive soils

摘要

It is known that mechanical properties of cohesive soils, which arc determined within the scope of geotechnical investigations, depend on the water content, while the latter mostly on the mineral composition of soils. These relationships are given as empirical expressions that are based on the results of laboratory tests performed on artificial monomineral clay mixtures. The aim of the investigations described in the article was to verify practical applications for the above-mentioned findings. Five samples of heterogeneous soils were tested for this purpose. The values of the geomechanical properties, which were calculated from selected mineralogical properties, are compared to experimentally tested values. The testing results show good correlation.
