    Experimental and Numerical Studies of Strip Footings on Geogrid-Reinforced Sand Slope
    (Springer Heidelberg, 2014) Keskin, M. Salih; Laman, Mustafa
    An experimental investigation into the ultimate bearing capacity of the strip footings resting on a sand slope with and without geogrid reinforcement is reported. The parameters investigated are the effect of the depth of the single layer of geogrid, vertical spacing of geogrid layers, number of geogrid layers, length of geogrid layers, the effects of the angle of the slope inclination, the relative density of sand, and type of reinforcement. A group of finite-element analyses was also carried out on a model slope. The results proved that the reinforcement had a considerable effect on the ultimate bearing capacity of the strip footings on a sand slope. The improvement in the bearing capacity of the strip footing on a reinforced slope was found to be strongly dependent on the slope angle, the relative density of sand, and the tensile strength of geogrid reinforcement. A satisfactory agreement between the experimental and numerical test results on a general trend of behaviour and optimum geometry of reinforcement placement is observed. Based on the model test results and the finite-element analyses, optimum values of the geogrid parameters for maximum reinforcing effect are discussed and suggested.

    Kuma Oturan Yüzeysel Temellerde Temel Boyutunun Taşıma Kapasitesine Etkisi
    (Çukurova Üniversitesi, 2012) Keskin, M. Salih; Laman, Mustafa; Uğur, Samet; Bildik, Selçuk
    Bu çalışmada, kumlu zeminler üzerine oturan şerit temellerin taşıma kapasitesi sayısal ve teorik olarak analiz edilmiştir. Bu amaçla, kum zemine oturan bir şerit temel modeli oluşturularak üç boyutlu Plaxis3D bilgisayar programı ve literatürdeki mevcut teorik yöntem (Terzaghi Yöntemi) kullanılarak analizler gerçekleştirilmiştir. Sayısal analizlerde, farklı temel genişlikleri kullanılarak, temel genişliğinin, taşıma kapasitesi, qu ve taşıma gücü katsayısına, N? etkisi incelenmiş ve teorik yöntemle karşılaştırmalar yapılmıştır. Sayısal analiz sonuçları, temel genişliğinin artmasıyla şerit temelin taşıma kapasitesinin arttığını, taşıma kapasitesi katsayısının ise azaldığını göstermiştir

    Model studies of bearing capacity of strip footing on sand slope
    (Korean Society Of Civil Engineers-Ksce, 2013) Keskin, M. Salih; Laman, Mustafa
    An experimental investigation into the ultimate bearing capacity of strip footing on sand slope is reported. The parameters investigated are the effect of setback distance of the footing to the slope crest, slope angle, relative density of sand and footing width on the ultimate bearing capacity of strip footings. A series of finite element analyses was additionally performed on a prototype slope to ascertain the validity of the findings from the laboratory model tests and to supplement the results of the model tests. The agreement between observed and computed results is found to be reasonably well in terms of load-settlement and general trend of behavior. The results show that the ultimate bearing capacity increases with increase in setback distance, relative density of sand, footing width and decrease in slope angle. At a setback distance of five times of the width of the footing, bearing capacity remains constant like that of a footing on level ground.
