Türkiye Kentsel Katı Atık Kompozisyonunun Kayma Mukavemeti Özellikleri ve Şev Duraylılığının İncelenmesi

Abstract

Gelişen dünya nüfusuna paralel olarak kentsel katı atık miktarı her geçen gün artmaktadır. Mühendislik özellikleri iyi tanımlanmamış katı atıklar ile yapılan kontrolsüz depolamalar sonucu oluşan göçmeler can güvenliğini tehlikeye atmakta ve büyük ekonomik kayıplara neden olmaktadır. Bu çalışmada laboratuvar koşullarında belirli kompozisyonlarda sentetik olarak üretilmiş ve doğal atık depolama sahasından alınmış taze ve yıllanmış kentsel katı atık (KKA) numunelerinin doğal su içeriği, organik madde miktarı, özgül ağırlık ve pH değerleri belirlenmiştir. Doğal ve sentetik KKA numunelerinin kayma mukavemeti parametreleri büyük ölçekli direk kesme cihazıyla belirlenmiştir. Elde edilen mühendislik parametreleri kullanılarak mevcut ve tasarlanmış KKA şevlerinin duraylılık analizleri yapılarak statik ve dinamik koşullar altında güvenlik sayıları belirlenmiştir. Çalışmadan elde edilen Türkiye KKA kompozisyonuna ait mühendislik parametreleri ve duraylılık analizleri sonuçları kullanılarak, Türkiye’de daha güvenli ve ekonomik KKA depolama sahalarının tasarımı yapılabilir.

Investigation of Shear Strength and Slope Stability of Turkish Municipal Solid Waste Composition

Abstract

In parallel with the developing world population, the amount of urban solid waste increases day by day. Uncontrolled storage of solid wastes with poorly defined engineering properties can result in a risk of life safety and serious economic loss. In this study, natural water content, organic matter content, specific gravity and pH values of the synthetic waste (with pre-determined compositions) and natural waste samples were investigated in laboratory conditions. Shear strength parameters of the synthetic and natural municipal solid waste (MSW) samples were determined by using a large scale direct shear test system. The slope stability analyses were conducted for present slopes at static and dynamic conditions and the factor of safety values were obtained. The obtained Turkey MSW composition engineering parameters can be used in the design of safe and economical MSW storage areas in Turkey.
