摘要

The aim of this study is to determine the relationships between different engineering properties of soils using the Dynamic Cone Penetration test (DCP). In this context, various correlation equations were created based on DCP results and data obtained from California Bearing Ratio (CBR) tests, Unconfined Compression Test (UCS), Direct Shear Test, and Bending Element Test. The portability, economic feasibility and simple operating principle of the DCP device facilitate on-site measurements and make it an attractive tool in geotechnical engineering. For this reason, the DCP test is a test that can be widely used to evaluate the in-situ properties of soils. Especially in cases where it is difficult to obtain undisturbed soil samples in loose or water-saturated sandy soils, the DCP test can be effectively used to predict the engineering properties of soils. Although there is extensive work in the literature on the DCP test to determine the strength and compressibility properties of soils, studies on the determination of dynamic properties are limited. In this context, soil samples of different qualities were taken from 30 different locations, and various engineering properties of the soils were determined. The results obtained from the study show that especially the strength and dynamic parameters of soils can be predicted with a high correlation with the DCP test.
