On Shear Strength of Stabilized Dredged Soil from İzmir Bay
Abstract Dredging is the process of carrying out work such as protection of inland water and sea lanes, construction/deepening of port basins, opening/deepening of channels and regulation of coasts. As a result of the dredging, the large amount of dredged soil is removed and disposal or reuse of this material is very important for economically and environmentally. This material can be recycled in the civil engineering applications as construction material, road and foundation embankment. However, because of the high organic matter content, dredged soil has very different shear strength characteristic compared to inorganic soil. In this study physico chemical engineering properties and shear strength behavior of natural and stabilized İzmir Bay’s dredged soil were examined for four organic matter contents (0%, 4%, 7% and 11%). The index properties of natural samples were defined by sieve analysis, specific gravity, Atterberg limits and pH tests. The direct shear tests were conducted with natural and stabilized dredged soils for saturated loose and dense samples. The shear strength parameters of natural dredged soils were compared with lime and silica fume added (10% and 20%) samples. Test results have shown that specific gravity value decreased, the liquid and plastic limit increased with the organic matter content increasing for natural samples. Silica fume added samples have higher cohesion but lower internal friction angles. The highest internal friction angle belongs to natural dredged soil without organic matter.
