Özet

Measurement or prediction of compression index ( C c ) of soils is essential for assessment of total and differential settlement of structures. It is a well-known fact that this parameter is controlled by several index identifiers of soil including initial void ratio, Atterberg limits, overconsolidation ratio, specific gravity, etc. Many studies in the past proposed relationships for prediction of C c based on different index properties. Therefore, this study aims to present a comparison of previously proposed equations for estimation of C c . Data from literature was compiled, and a total of 90 and 623 test results on remolded and undisturbed specimens were used to question the validity of previously proposed equations. Nevertheless, the modeling ability of 7 and 12 equations for estimation of C c of remolded and undisturbed soils were questioned by use of compiled data. Moreover, new empirical relationships based on initial void ratio and toughness limit for prediction of C c was proposed by use of nonlinear multivariable regression and evolutionary based regression analyses. The results are promising -the performances of models established are quite acceptable, which are verified by statistical analyses.
