Comparison of fine-grained soils of the Kolsuz and Arapl areas in the Central Anatolia (Nigde, Turkey) in terms of geotechnical properties.

摘要

Clayey soils are used in various industrial applications as raw material. However, they are also used both as materials and soils on which constructions are built in the geotechnical engineering. Therefore, estimation of soil behavior in terms of design is vital. In this context, it is necessary to determine the engineering properties of the soils. There are voluminous study on the geology, mineralogy and chemistry of the clayey soils in the Central Anatolia, Nigde (Turkey). However, not many studies deal with their geotechnical properties. In the current study, the engineering properties of clayey soils are determined through laboratory tests on the clayey soil samples taken from the Arapl and Kolsuz areas and also the comparison is made between clayey soils in the Arapl and Kolsuz areas considering their geotechnical properties. As a result, it is observed that the fine-grained soils of the Kolsuz area are inactive and have low plasticity (CL) with average w_L of 32 and w_P of 19. The fine-grained soils of the Arapl area have high plasticity (MH) with average w_L of 96 and w_P of 57 and are active. It is also found that while the fine grained soils of the Kolsuz area has almost no swelling potential, those of the Arapl area has high swelling potential based on their mineralogical contents, consistency limits, activities and swelling pressures.
