Abstract (EN)

In this study, the bearing capacity and settlement behavior of shallow foundations on reinforced granular fill layer over soft clay soil were investigated using a small scale field and laboratory tests. Circular foundations with the diameters of 6cm, 9cm and 12cm and square footing with dimensions of 15.2cm×15.2cm were used in the tests. Geogrids used as reinforcement were placed in granular fill bed compacted over clay soil. The effects of parameters such as thickness of the granular fill layer, the location of the first geogrid layer, the vertical spacing of geogrid layers and the number of geogrid layers on bearing capacity and settlement were investigated in the tests. After the tests, numerical analyses were carried out with finite element based two and three dimensional software PLAXIS and ABAQUS, the results obtained were compared with experimental results. Scale effect analyses with foundation sizes were conducted and some statistical relations were suggested.Keywords: Field and laboratory tests, clay soil, Granular fill bed, Geogrid, Scale effect.
