Abstract

In this research, the shear strength of the blue-green soft silty-clays in Konyaalti (Antalya) has been investigated. Samples taken in every 0.5 m from boreholes were investigated using laboratory methods. Additionally, CPT and SPT tests were conducted near the boreholes. Some important correlations have been established between undrained shear strength (S-u), physical soil properties and in-situ test results, in order to develop predictive models. As a result of statistical analysis of correlations between undrained shear strength-overconsolidation ratio and dry unit weight, high correlation coefficients were obtained. Besides the laboratory tests, Standard Penetration and Cone Penetration tests results were correlated with undrained-unconsolidated triaxial test results to predict (S-u). Finally, an empirical model to predict S-u were developed.
