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.
