A new durability assessment method of the tuffs used in some historical buildings of Cappadocia (Turkey)
Deniz, B. Ertas; Topal, Tamer (2021-04-01)
Cappadocia region in Turkey is known as a touristic and historical area with volcanic rocks formed by the effect of intense Neogene calcalkaline volcanism. Rhyolitic to trachyandesitic tuffs, being widespread as a volcanic...
Effect of disturbed zone thickness on rock slope stability
Ersöz, Timur; Ozkose, Merve; Topal, Tamer (2021-04-01)
Cut slope surfaces are affected by excavation activities and weathering agents. Disturbances on the surface can penetrate down to a certain depth. Slope stability analyses made on the cut slopes can reveal unsatisfactory r...
