Correlation Study Between PMT and SPT Results of Artificially Filled Area

Abstract

The non-linear nature of the soils can cause the parameters to change significantly even in a limited area. In site investigation studies, the sampling frequency is important in determining soil properties with sufficient accuracy and in developing an idealized soil profile in which the engineering design will be made. Statistical methods are used in cases where field studies cannot be done adequately due to technical limitations, unsuitability of the study area and cost problems. These methods usually provide important information about the soil at the preliminary design stage. While statistical methods are used by researchers and practitioners to obtain soil parameters, no study has been found in the literature on the use of these methods in artificially filled areas. In this study, the soil parameters of the filled area created in the Yenikapı, İstanbul with an area of 715.000 m 2 were examined. In this context, empirical correlations have been developed between the parameters obtained by the geotechnical tests carried out and the relationships between the soil parameters have been revealed. The data obtained from pressuremeter and standart penetration tests were used in correlations. The developed correlations were compared with the empirical correlations developed for natural soils and important findings were obtained.
