There has been explored the system of helical piles and its behaviour in compression. There have been examined principles of loads transmission mechanics on soil. There have been examined three calculation methods which are provided for determination of helical pile capacity. There has been analyzed helical screw pile in four different soils with different amount of capacitive plates. During the analysis of screw piles activity there have been found some correlations which can be used to determine the most useful screw pile in terms of economics and rationalization. As none of the methods mentioned above does not examine deformation of screw pile as well as not giving any calculation or evaluation principles, the calculation finite element model is developed. Has been observed the interaction between screw pile and soil in different soils with specified loads with one or two capacitive plates.
