Comparison of methods in calculating the bearing capacity of the foundation

When we build buildings we often encounter shallow foundations because it is more economical and easier to build than on deep foundations, this will be a mistake that will create high risk for the building itself and the community in general. The main purpose of this paper is to compare the bearing capacity calculation methods proposed by different authors and design geotechnical Eurocodes. To achieve the purpose of the study, Terzaghi (1943), Meyerhof (1963), Eurocode EC-7 (1996/2004) taking into account the analysis of physical-mechanical parameters for calculating the bearing capacity of the foundation where the placement of loads is foreseen where defined depth of finite Df. The bearing capacity factor of the foundation, geomechanical analysis and equations are presented in this paper. The most important conclusion in this paper is that the bearing capacity of the soil depends very much on the method used and the parameters of soil hardness such as the internal friction angle ϕo cohesion C and the modulus of soil compaction Es
