Classification and modification of slake durability test for different types of rocks Ersöz, Timur; Topal, Tamer (2024-04-01) Rocks exposed to atmospheric conditions are subjected to weathering processes driven by numerous factors especially precipitation. The slaking behavior attributed to water-induced weathering particularly affects rocks cont...
Assessment of geoenvironmental problems at Hasankeyf Antique City (Türkiye) Topal, Tamer; Kaya, Y. (2024-01-01) The Hasankeyf Antique City contains several historical structures, ancient and new man-made caves. The dolomitic limestone exposed in the area is the main rock, but weak and not durable. The rock is deteriorated under envi...
A new quantitative welding degree classification for ignimbrites Akin, Mutluhan; Topal, Tamer; Dinçer, İsmail; AKIN, MÜGE; Özvan, Ali; Orhan, Ahmet; Orhan, Ayşe (2023-07-01) As a pyroclastic rock type, ignimbrites may reveal varying degrees of welding depending on the temperature (> 535 ℃) and overburden pressure conditions during its formation. The welding degree of ignimbrites increases as t...
İgnimbiritlerde Pomza Şekli ile Fiziksel-Mekanik Özellikler Arasındaki İlişkilerin İncelenmesi Akın, Mutluhan; Topal, Tamer; Dinçer, İsmail; Akın, Müge; Özvan, Ali; Orhan, Ayşe; Orhan, Ahmet (2022-06-01) Piroklastik bir kaya türü olan ignimbirit yüksek derecede gözenekli olmasından dolayı ısı ve ses yalıtımı özelliğine sahiptir. Ayrıca oluşumları esnasında kazandıkları estetik dokusal özellikleri ve hafif oluşları sebebiyl...
Durability assessment of some Cappadocian tuffs using factor analysis, multiple regression analysis, and analytical hierarchy process Deniz, B. Ertas; Topal, Tamer (2022-01-01) Tuff located in Central Anatolia (Cappadocia) has been used as a building stone in many historical monuments, churches, and mosques. Although some of the tuffs used in those historical structures show good performances, th...
Effect of disturbed zone thickness on rock slope stability Ersöz, Timur; 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...
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...
Assessment of the effectiveness of a rockfall ditch through 3-D probabilistic rockfall simulations and automated image processing AKIN, MUTLUHAN; DİNÇER, İSMAİL; OK, ALİ ÖZGÜN; ORHAN, AHMET; AKIN, MÜGE; Topal, Tamer (2021-03-01) Rockfall ditches or catchment areas aim to collect falling blocks at the toe of a source zone by dissipating the energy of blocks in an excavated trench. The effectiveness of a rockfall ditch is simply expressed by its blo...
Assessment of damage zone thickness and wall convergence for tunnels excavated in strain-softening rock masses Satici, Ozguer; Topal, Tamer (2021-02-01) There are two fundamental issues in all underground excavations, which are safety and economy. To ensure safety and expedite excavations, level of tunnel wall convergences and damage zone thickness should be predicted befo...
The impact of cyclic loads on physicomechanical properties of the massive and vesicular basalts Dursun, Felat; Topal, Tamer (2020-11-10) Stone monuments are the most visible and essential structures of our cultural heritage; however, many of the historical structures around the world are now suffering from stone deterioration. Diyarbakır City Walls, which w...
