Nonlinear stress-strain analysis of terrain using the finite element method

This paper presents the stress-strain analysis of terrain using the finite element method in the settlement Medakovic in Belgrade during the construction and occupation of the eighth floor residential building. The slope stability analysis was performed using the finite element method. Application the finite element method, with the use of proposed incremental procedure has shown some advantages compared to the classical methods of stability analysis. First of all, using this method, it is possible to assess at any time the stress and strain values in terrain. Based on these values, it is possible to determine: zones of failure (local and/or general), critical sliding surface and reliable safety factor The obtained results are of great significance for the most part of the Belgrade terrain which was built up in a similar way and in the last few decades has been intensively urbanized. It has to be emphasized that the proposed stress-strain procedure has its application in construction of highways and landfills, both in civil engineering and mining engineering.
