Özet: Nowadays, especially in big cities, engineering structures are built for different purposes in residential areas. Before construction studies, geological environments which are form the basis of engineering structures should be investigated. Antalya is one of these settlements which on travertines and the settlement areas in Antalya are expanding. Unconsolidated levels of the travertine are called as tufa. Tufas generally are weak rock properties and it is difficult to obtain cores from tufas. It was observed that rock quality index (RQD) values were quite low in the in the basement drillings. In this study, the bearing capacity values of the travertine and tufa levels of different characteristics, which form the basement at the same level and depth, were determined by different tests in the laboratory and on the field (in-sıtu). According to the findings obtained, the bearing capacity values obtained in the laboratory (free pressure and point loading test) were very higher the bearing capacity obtained in the field (plate loading test). The reason for this is the analysis carried out on the rocks, which are relatively stronger in the laboratory than the field. As a result, it is appropriate to determine the bearing capacity values ın-sıtu testing in geological environments which are strength values change frequently such as tufas, in terms of the design and safety of the structures.
