Geosentetik Donatılı İstinat Duvarı ile Betonarme İstinat Duvarının Karşılaştırmalı Analizi: Kastamonu-Karabük Karayolu Örneği

Dolgu uygulaması karayolu ve demiryolu inşaatlarında sıklıkla karşılaşılan bir uygulamadır. Bu çalışmada dolgu stabilizasyonunu sağlamak amacıyla yapılan ve geleneksel sanat yapılarından olan betonarme istinat duvarı ile geosentetik (geogrid) donatılı istinat yapısı maliyet, yapım süresi, hizmete açılma süresi, estetiklik ve hizmet ömrü kriterleri dikkate alınarak karşılaştırmalı olarak analiz edilmiştir. Mukayeseler, Karayolları Genel Müdürlüğü (KGM) tarafından uygulama yapılmakta olan aynı karayolu üzerindeki farklı iki lokasyondaki mühendislik yapıları üzerinde yapılmıştır. Birinci lokasyonda mevcut geosentetik donatılı duvar yerine betonarme istinat duvarı projelendirilirken, ikinci lokasyonda ise mevcut betonarme istinat duvarı yerine geosentetik donatılı duvar projelendirilmiştir. KGM pozları doğrultusunda maliyet analizleri yapılmıştır. Özellikle yükseklik artışına paralel olarak geosentetik donatılı duvarların maliyet açısından avantajlı duruma geçtiği sonucuna ulaşılmıştır. Ayrıca hizmet ömrü, inşa süresi, kullanıma açılma süresi ve estetiklik kriterleri açısından performansları değerlendirildiğinde ise geosentetik donatılı duvarların daha avantajlı olduğu ortaya konulmuştur. Çalışma sonuçlarından elde edilen bilgilerin, yol çalışmalarında dolgu stabilite sorunu ortaya çıkan lokasyonlarda hem performans hem de maliyet açısından hangi sanat yapısının tercih edilmesinin daha uygun olacağının karar verilmesine katkı sunulacağı düşünülmektedir.

Comparative Analysis of Geosynthetic Reinforced Earth Wall and Reinforced Concrete Retaining Wall: Kastamonu-Karabuk Highway Case Study

Embankment is a frequently encountered application in road and railway constructions. In this study, reinforced concrete retaining wall, which is one of the traditional engineering structures and constructed to provide fill stabilization, and geosynthetic (geogrid) reinforced retaining structure were analyzed comparatively by considering cost, construction time, duration for service, service life, and aesthetics criteria. The comparisons were carried out on the engineering structures in two different locations on the same highway, which are under responsibility of the General Directorate of Highways (KGM). In the first location, a reinforced concrete retaining wall was designed instead of the existing geosynthetic reinforced wall, while a geosynthetic reinforced wall was designed instead of the existing reinforced concrete retaining wall in the second location. Cost analyses were made in line with KGM items. It was concluded that geosynthetic reinforced earth walls became advantageous in terms of cost, especially in parallel with the increase in height. In addition, it is revealed that geosynthetic reinforced walls are more advantageous when their performance is evaluated in terms of construction time, duration for service, service life and aesthetics criteria. It is thought that the data obtained from results of the study will contribute decision makers to decide the most appropriate engineering structure in terms of both performance and cost at the locations where filling stability problems arise in highway construction.
