Donatılı kum zemin üzerine oturan ring (halka) temellerin analizi

Bu çalışmada, deneylerde farklı çaplarda model halka temeller ile çift yönlü geogrid donatılar kullanılmıştır. Ayrıca, PLAXIS bilgisayar yazılımı kullanılarak halka temeller, sonlu elemanlar yöntemi ile analiz edilmiştir. Deney ve analiz sonuçlarından, donatılı ve donatısız durumda halka temellere ait nihai taşıma kapasiteleri belirlenmiştir. Sonuçta bu değerler birbirleriyle karşılaştırılmış ve her iki durum için optimum temel yarıçap oranları bulunmuştur.

Bearing capacity of ring foundations on geogrid-reinforced sand

In this study, the small-scale model ring foundations which have different ring width ratios were used for the tests and biaxial geogrids were used as reinforcement. The analysis of foundations were also carried out by using the finite-element program, PLAXIS. From the results of the tests and analysis, the values of the ultimate bearing capacity of model foundations with reinforcement and unreinforcement were obtained. Consequently, these results were compared with eachother and optimum ring width ratios were found.
