Landslides in Serbia, in most cases, are highly dependent on the existing geological conditions and each landslide has its own peculiarities that must be determined by geotechnical investigations. Therefore, the paper first presents the basic characteristics of landslides in Serbia and procedures for their research. In addition to the calculations for vertical piles used for landslide stabilization are presented. The calculation methodology is complex because it involves the interaction of landslide and stabilizing piles. The lateral resistance of the soil is calculated by Brinch Hansen method. It includes three-dimensional effects of surrounding soil and can be applied in complex geological conditions, which are very often in Serbia.
In the calculation process, both geotechnical and structural lateral bearing capacity of vertical piles are determined, while landslide stability is analyzed using the appropriate limit equilibrium methods.
The proposed calculation procedure assumes that a complete sliding surface, together with piles, contribute to a target value of the safety factor of the landslide.
