Abstract:

 

The most common natural disaster type in our country is landslide. Most of the structural damage occur due to the landslides after earthquake damages. Landslide events were observed along The Çankırı-Ankara State Road intensively. Especially in 2012 Spring, a lot of new landslide events were observed. In this study, data on geological and topographical factors related to landslide occurrence in the investigated area were collected and landslide risk groups were determined by using frequency ratio method. Landslide susceptibility map of the study area has been created according to these groups, so therefore aimed to identify risk areas where measures to be taken in the highway construction. Most risky areas are the region between Akyurt-Kalecik turn and near surroundings of Çankırı. Active landslides occurred in the area opened on the road cut in the risk zone.

 


Heyelanlar, ülkemizde en sık karşılaşılan doğal afet türlerinden biridir. Depremlerden sonra en çok yapı hasarı da yine heyelanlar nedeniyle meydana gelmektedir. Çankırı-Ankara karayolunda (Akyurt-Çankırı arası) heyelan olayları yoğun olarak yaşanmaktadır ve özellikle 2012 yılı bahar aylarında pek çok yeni heyelan ve toprak kayması olayı gözlenmiştir.Bu çalışmada incelenen alanda heyelan oluşumu ile ilgili jeolojik ve topografik unsurlara ait veriler toplanıp frekans oranı metodu kullanılarak heyelan risk grupları belirlenmiştir. Bu gruplara göre çalışma alanının heyelan duyarlılık haritası oluşturulmuş, böylece riskli alanları dolayısıyla karayolu yapımında önlem alınması gereken yerleri belirlemek amaçlanmıştır.Akyurt-Kalecik sapağı arasında kalan bölge ve Çankırı yakın çevresi heyelan riskinin en fazla olduğu bölgeler olarak tespit edilmiştir. Alandaki aktif heyelanlar bu riskli bölgelerde açılan yol yarmaları üzerinde oluşmuştur.Anahtar Kelimeler: Heyelan, Çankırı-Ankara karayolu, heyelan duyarlılık haritası, frekans oranı metodu


Abstract

Identification of Landslide Risk Zones Along The Çankırı-Ankara (Between Akyurt and Çankırı) State Road

The most common natural disaster type in our country is landslide. Most of the structural damage occur due to the landslides after earthquake damages. Landslide events were observed along The Çankırı-Ankara State Road intensively. Especially in 2012 Spring, a lot of new landslide events were observed.In this study, data on geological and topographical factors related to landslide occurrence in the investigated area were collected and landslide risk groups were determined by using frequency ratio method. Landslide susceptibility map of the study area has been created according to these groups, so therefore aimed to identify risk areas where measures to be taken in the highway construction.Most risky areas are the region between Akyurt-Kalecik turn and near surroundings of Çankırı. Active landslides occurred in the area opened on the road cut in the risk zone.Keywords: Landslide, Çankırı-Ankara State Road, landslide susceptibility map, frequency ratio method
