PROBLEMS OF SOILS NONHOMOGENEITY

ABSTRACT

Soils constitute the subgrade of many building objects. There is thus a justified need to identify the nonhomogeneity of soil parameters. Parameters used in engineering calculations e.g. when checking the limit state (load-bearing capacity and serviceability). The present work gives an assessment of soil nonhomogeneity, Tetiary (Pliocene) clays being taken as an example. Their microstructures, granulometric composition and major engineering-geological features have been analyzed. In the assessment of nonhomogeneity both the coefficient of nonhomogeneity/changeability and the Kagan coefficient have been considered. In the Tables listed are concrete values of the above coefficients. Particular attention has been given to the Kagan coefficient of general nonhomogeneity. Finally, critical values of the nonhomogeneity coefficient γ_m have been suggested (in Table 4) which can be used for the assessment of soil nonhomogeneity depending on the parameter (feature) analyzed.

Key words: nonhomogeneity, soils, properties, subsoil, capacity.
