Farklı Havza Sularının Killerin Kıvam ve Mukavemet Özellikleri Üzerindeki Etkisinin Araştırılması

Abstract

The engineering behavior of clay soils, vary depending on the amount of water they contain. These variations depend on the crystal structure of the clay mineral and the chemical structure of the water in the voids of the soil. In this study, on the geotechnical properties of high plasticity (CH) and low plasticity (CL) clays the effects of waters with different chemical structures were investigated. Within the scope of the study, some geotechnical experiments were carried out on two different clays from Erzurum with high plasticity and low plasticity and, tap water and water with different chemical structures obtained from three different basin in Eastern Anatolia (Fırat Basin, Çoruh Basin and Aras Basin) were used. The consistency limits, standard proctor and unconfined compression tests were carried out on clays, and the experiments were repeated using different basin waters and, the results were compared with the test results with tap water. The test results showed that different waters significantly changed the consistency and compaction properties of high and low plasticity clays and that they did not cause a significant change in unconfined compression strength. Çoruh Basin reduced the liquid limit of the CH and CL clays of the water by 33% and 20%, respectively. With the effect of the Çoruh Basin, the optimum moisture content of the CH clay decreased by 41.2%, while the optimum moisture content of the CL clay increased by 52.7% with the effect of the Fırat Basin.
