ÖzetBu çalışmada, dikdörtgen kesitli model temelin farklı yükleme koşullarında zemine oturması sonucunda meydana gelen düşey gerilme ve taşıma gücü değişimleri deneysel ve teorik olarak araştırılmıştır. Merkez ve eksantrik yüklemeler altında ilave düşey gerilme artışları derinlik boyunca yatayda yerleştirilen gerilme ölçer vasıtasıyla laboratuvar ortamında model deneyler yapılarak ölçülmüştür. Ayrıca yük-oturma değerleri de yük hücresi ve deplasman ölçerler vasıtasıyla elde edilmiştir. Daha sonra deney sonuçları, literatürde mevcut teorik yöntemlerle (Boussinesq, Westergaard ve 2:1 Yöntemi) karşılaştırılmıştır. Deneylerde gevşek kum zemin kullanılmıştır. Deneyler, İskenderun Teknik Üniversitesi İnşaat Mühendisliği Bölümü Geoteknik Laboratuvarı'nda yapılmıştır. Deney sonuçları, eksantrisite arttıkça taşıma gücü değerlerinin azaldığını göstermiştir. Aynı zamanda merkezden uzaklaşıldıkça da gerilme değerlerinde azalmalar tespit edilmiştir. Model deney sonuçları ile teorik sonuçların da birbirleri ile uyumlu oldukları belirlenmiştir.Anahtar Kelimeler: Model deney, İlave düşey gerilme, Gerilme ölçer, Dikdörtgen temel, Merkez yükleme, Eksantrik yükleme Stress and Bearing Capacity Analyses under Rectangular Footing AbstractIn this study, the stress and the bearing capacity changes were experimentally and theoretically investigated in different loading conditions using rectangular model footing. The stress distribution was vertically obtained with the laboratory tests in central and eccentrically loading conditions using stress transducers. And also the load-settlement curves were obtained with load cell and displacement transducer. The test results were compared with theoretical results (Boussinesq, Westergaard and 2:1 Method). The loose sand was used during the tests. The model tests were conducted in the Geotechnical Laboratory of Civil Engineering Department of Iskenderun Technical University. The test results showed that the bearing capacity decreases with an increase in the load eccentricity. Also the stress values decrease while moving away from the center of the model footing. As seen that the model test results are compatible with the theoretical results each other.

“…The improvement of the bearing capacity of eccentrically loaded shallow foundations was the main objective of several investigations, especially when the reinforcing material is geotextile, e.g. Badakhshan and Noorzad [12], Patra et al [13], Sahu et al [14] and Saran et al [15].…”

This paper presents the results obtained from an experimental programme and numerical investigations conducted on model tests of strip footing resting on reinforced and unreinforced sand slopes. The study focused on the determination of ultimate bearing capacity of strip footing subjected to eccentric load located either towards or opposite to the slope facing. Strip footing models were tested under different eccentricities of vertical load. The obtained results from tests conducted on unreinforced sand slope showed that the increase in eccentricity of applied load towards the slope facing decreases the ultimate bearing capacity of footing. Predictions of the ultimate bearing capacity obtained by the effective width rule are in good agreement with those proposed from the consideration of total width of footing subjected to eccentric load. The ultimate bearing capacity of an eccentrically loaded footing on a reinforced sand slope can be derived from that of axially loaded footing resting on horizontal sand ground when adopting the effective width rule and the coefficient of reduction due to the slope. When increasing the distance between the footing border to the slope crest, for unreinforced and reinforced ground slope by geogrids, the ultimate bearing capacity of footing is no more affected by the slope ground.

“…This was occurred by removing the weak soil up to a certain depth and then exchanging the soil or fills the same soil back with the implying of horizontal sheets of geosynthetics at different depths under the footing. Therefore, with the advantages of using soil reinforcement both the type and the size of foundation may be changed causative an economic design [2][3][4][5][6][7][8][9].…”

This study investigates the "bearing capacity" of a strip footing subjected to inclined and "eccentric load" on geogrid reinforced sandy soil by using physical modeling. The effect of each of the "depth ratio" of the first sheet of reinforcement, the vertical space ratio between consecutive sheets, number of reinforcement sheets, and the effective "depth ratio" of reinforcement on the "bearing capacity" were investigated. Also, the combined effect of load inclination angle, eccentricity ratio of the load and the relative density on the ultimate "bearing capacity" were studied. The results illustrated that by increasing the number of reinforcement sheets, the "bearing capacity" increased, but there is an optimum value (4-5). The optimum "depth ratio" of the first sheet of reinforcement was 0.35B. The optimum vertical space ratio between consecutive sheets was 0.25B. Using a test results with helping a statically analysis software program, a new easy and reliable empirical equation for computing the ultimate "bearing capacity" of the strip footing subject to inclined and eccentric load supported on geogrid reinforced sandy soil was developed.
