A geoengineering evaluation of antique underground rock settlements in frig (Phrygian) valley in the afyon-kütahya region of Turkey

Abstract

In this study, the seismicity and state of stress of the region, climatic conditions in underground openings and their vicinity, short-termmechanical behaviour of the surrounding rocks, their index and mechanical properties were studied. Furthermore, the effect of water content and size of samples on mechanical properties were investigated. The outcomes of these studies are presented and dicussed in this article. This study is propably the first geo-engineering study of the underground settlements in Frig Valley and it is anticipated to initiate similar studies on this forgotten area of Turkey in future. © 2016 Taylor & Francis Group, London.
