Abstract

İzmir Körfezi'nin Batı sahilinde
Meles çayı, Arap ve Manda dereleri tarafından taşınmış yaklaşık 3 milyon
metreküp kirlenmiş alüvyonel zemin bulunmaktadır. Bu akarsular, 300.000 m2‘lik
bir deltayı paylaşmaktadır. Deltada bulunan alüvyonlar 10 ila 15 m kalınlığında
yüksek su içeriği ve düşük taşıma kapasitesine sahip katmanlardan oluşmaktadır.
Meles deltası zaman içerisinde, büyük ölçekli konut inşaat projelerinin
yapımının başladığı şehrin doğu sahil şeridi içinde kalmıştır. Geniş bir alan
işgal eden ve rekreasyon çalışmaları için bile uygun olmayan bu yumuşak
birikintilerinin maliyet etkin bir şekilde stabilizasyonuna ihtiyaç
duyulmaktadır. Ayrıca, yolcu gemilerinin İzmir Limanı'na yaklaşma kanalını
derinleştirmek için delta alanının deniz dibi kısmının da taranması
planlanmaktadır. Tarama yolu ile toplanacak kirlenmiş deniz sedimentlerinin
depolanması da ayrıca çevresel bir sorun oluşturmaktadır. Bu çalışmada, kireç,
çimento ve bunların farklı oranlarda karışımları kullanılarak, Meles Deltası
zeminlerinin stabilizasyonu hedeflenmiştir. Optimum katkı oranlarını belirlemek
için tek eksenli basınç deneyleri yapılmıştır. Stabilizasyon ürünlerini ve
mikro yapıdaki değişiklikleri gözlemlemek için stabilize edilmiş zemin
numunelerinde X-ışını kırınım (XRD) testleri ve taramalı elektron mikroskobu
görüntülemesi (SEM) yapılmıştır. X-ışını testlerinde değişik oranlarda
stabilizasyon ürünleri tespit edilmiştir. Ayrıca, işlenmemiş ve stabilize
edilmiş zemin örneklerinin SEM görüntülerinin karşılaştırılması, mikro yapıda
kalsiyum alümina hidratlar ve kalsiyum silika hidratların varlığını ortaya
koymuştur.

SEM and XRD Analyses of Stabilized East Coastline Delta Soils of Izmir Bay Area

Abstract




The gulf of İzmir contains 3
million cubic meters of polluted sediments carried by Meles, Arap and Manda
rivers. These rivers share the same delta with a surface area approximately
300.000 m2, where 10 to 15 m thick sediment layers were deposited
with high water content and low bearing capacity. The delta is now located
along the east coastline of the city, where large scale residential building
projects are under construction. These soil deposits that are unsuitable for
the establishment of recreational facilities need to be stabilized in a
cost-effective way. Besides, the sea bottom portion of the delta area will be
dredged in order to deepen the approach channel of the cruise ships to the Izmir
Port. The disposal of the contaminated sea sediments has also become an
environmental concern. In this study, lime and cement and their mixtures with
varying portions were considered as a stabilization agent for soft and
contaminated sediments. Unconfined compression tests were conducted in order
to determine the optimum additive percentages. X-ray diffraction tests (XRD)
and scan electron microscope (SEM) imaging were performed on the stabilized
soil specimens in order to observe the cementitious products and changes in
the micro structure. In X-ray tests, cementitious by-products were detected
in varying ratios. Also, the comparison of SEM images of untreated and
stabilized soil specimens reveals the presence of calcium alumina hydrates
and calcium silica hydrates in the micro structure.
