چکیده    Many studies have been carried out in recent years on estimating consolidation properties of clays from their plastic and index properties,and to prefigure about consolidation behaviour of soils. the simple empirical equations between these parameters can be calculated and applied to specific soil types easily,thus saving time on estimating the consolidation properties of soils prior to detailed laboratory tests. although there are quite a number of studies presented in the literature,most of these studies have been done on pure clays (e.g. glass clay),which restrict the applicability of the calculated equations. in this study,a different approach was applied to the clayey soils near cevizdere region in ünye (ordu,turkey),and the consolidation properties via standard one dimensional consolidation (oedometer) test,atterberg limits,specific gravities,grain size distribution via wet sieve analysis and hydrometer tests,and the type of clay minerals via x-ray diffraction (xrd) analyses of 15 natural soil samples were determined. the soil samples overall consist of 28% sand-sized,38% silt-sized,and 34% clay-sized particles. the liquid limits of the samples vary between 63% and 76%,and plastic limits between 24% and 34%. according to the iaeg (1976) plasticity classification,the soil samples are classified as highly-very highly plastic. the xrd analyses show the clay minerals in the soil samples are of montmorillonite type. the oedometer test results indicate that the soil samples have compression index (cc) values ranging between 0.189 and 0.625,re-compression index (cr) values ranging between 0.011 and 0.041,and over-consolidation ratio (ocr) values ranging between 4.16 and 95. the studied soil is classified as moderately-highly over-consolidated according to the over-consolidation limit classification. the pre-consolidation stresses and liquid limits of the soil samples were investigated statistically and the coefficient of correlation is calculated as 0.5. © 2016,tmmob - jeoloji muhendisleri odasi. all rights reserved.
