Farklı Havza Sularının Killerin Kıvam ve Mukavemet Özellikleri Üzerindeki Etkisinin Araştırılması

Kil zeminlerin mühendisllik özellikleri içerdikleri su miktarına bağlı olarak değişiklik göstermektedir. Bu değişiklikler, kil mineralinin kristal yapısına ve zeminin boşluklarında yer alan suyun kimyasal yapısına bağlıdır. Bu çalışmada, farklı kimyasal yapıda suların, yüksek plastisiteli ve düşük plastisiteli killerin geoteknik özelliklerine olan etkisi araştırılmıştır. Çalışma kapsamında, Erzurum’dan temin edilen yüksek plastisiteli ve düşük plastisiteli iki farklı kil üzerinde bazı geoteknik deneyler gerçekleştirilmiş ve deneylerde çeşme suyu ile Doğu Anadolu Bölgesi’nde bulunan üç farklı su havzasından (Fırat Havzası, Çoruh Havzası ve Aras Havzası) temin edilen farklı kimyasal yapılara sahip sular kullanılmıştır. Killer üzerinde kıvam limitleri, standart proktor ve serbest basınç deneyleri yapılmış, deneyler farklı havza suları kullanılarak tekrarlanmış ve sonuçlar çeşme suyu ile yapılan deney sonuçları ile karşılaştırılmıştır. Deney sonuçları, farklı suların, yüksek ve düşük plastisiteli killerin kıvam ve kompaksiyon özelliklerini belirgin olarak değiştirdiğini, serbest basınç mukavemetlerinde ise belirgin bir değişim meydana getirmediğini göstermiştir.

Investigating The Effects of Waters Collected From Different Basins In Turkey on Clays’ Consistency And Strength Properties

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