AB  - Bu çalışma kapsamında Yeniyol (Borçka-Artvin)Mahallesi’deki yeni devlet hastanesinin inşaatı için açılan zemin şevindemeydana gelen duraysızlık problemi mühendislik jeolojisi açısındanincelenmiştir. Yapılan çalışmalar sırasıyla arazi, laboratuvar ve duraylılıkanalizi çalışmaları olmak üzere üç aşamada yürütülmüştür. Bu amaçla toplam 108m derinliğinde 3 adet sondaj kuyusu açılmış, 1 profilde jeofizik çalışmalargerçekleştirilmiş ve 1 sondaj kuyusunda inklinometre ölçümleri yapılmıştır.Arazi çalışmaları sonucunda ana kayayı Eosen yaşlı Kabaköy Formasyonu’na ait volkanikkayaçların oluşturduğu ve bu birimlerin üzerine alttan üstte doğrukumlu-çakıllı ve killi-siltli olmak üzere iki seviyeden oluşan yamaç molozunungeldiği saptanmıştır. Yamaç molozunun fiziko-mekanik özelliklerini belirlemekiçin araştırma sondajlarından örselenmemiş örnekler alınmıştır. Arazi velaboratuvar çalışmalarından elde edilen veriler yardımıyla sonlu elemanlartabanlı 2D ve 3D Kayma Dayanımı Azaltma Yaklaşımı (FEM-SSR) yöntemlerikullanılarak duraylılık analizleri yapılmış ve sonuçlarının birbiriyle uyumluolduğu saptanmıştır. Sonuç olarak kazı şevinde önlem alınmaması durumunda önünegeçilemez mühendislik sorunlarıyla karşılaşılacağı belirlenmiştir. Desteklemeyöntemi olarak ise forekazık uygulamasının yapılması önerilmektedir.

N2  - In the scopeof this study, the stability problem in the soil slope excavated for theconstruction of the new government hospital in the Yeniyol (Borçka-Artvin) quarterwas investigated in terms of engineering geology. The studies were performed inthree stages as field, laboratory works and stability analyses. For thispurpose, three boreholes with a total of 108 meters in length were drilled,geophysical studies were performed along the one line and inclinometermeasurements were taken in one borehole. The talus consisting of two levels assandy-gravelly and silty-clayey soils overlies the Eocene-aged KabaköyFormation comprising the volcanic rocks. To determine the physico-mechanicalproperties of talus, undisturbed samples were taken from boreholes. 2D and 3D FEM-SSRstability analyses were evaluated using the obtained data from field andlaboratory studies. It was determined that the stability analyses results are compatiblewith each other. As a result, it was determined that unforeseen engineeringproblems will be encountered if measures are not taken in the slope. It issuggested to apply fore pile application as support method.
