Predicting Geotechnical Parameters of Fine-Grained Dredge Materials of the Gulf of Izmit (NW of Turkey) Using the Slump Test Method and Index Property Correlations

摘要

In this study, an attempt has been done to figure out the geotechnical properties of physically remolded dredged materials of the Gulf of Izmit located in NW of Turkey, by using slump test method. For this aim, slum tests were conducted on dredge material samples using open-ended polyvinyl chloride (PVC) cylinders of 10cm diameter and hight. Material properties of dredged material samples including grain size distribution, Atterberg limits, water content, specific gravity, bulk density, percent solids, bulk wet density, permeability and void ratio, and engineering behavior properties such as Vane shear strength, and effective stress were determined. Water content of the dredge material samples was obtained in the laboratory using oven method. Later, the statistical correlations were conducted by regression analysis to obtain the relationships between water content and slump/cylinder height as well as other parameters such as bulk wet density, % solid by weight, void ratio, Vane shear strength and effective stress.
