The master's thesis deals with various calculation methods for determining the pile bearing capacity in compression, with an emphasis on the end bearing capacity in cohesionless soil, for which different values are obtained according to different authors.
The first part of the thesis presents the types of piles and the factors that most influence the bearing capacity of piles (installation method, load transfer, pile settlements). The second part of the thesis presents the Eurocode 7 design principle, with an emphasis on geotechnical structures and pile foundation. Various approaches are given for the estimation of the pile load capacity in compression – directly from field investigations, from static and dynamic pile load tests, by analytical and empirical methods. Emphasis is placed on different analytical and empirical methods according to different authors, especially on the determination of the end pile resistance in sandy soil. For the selected methods, which are the most used in Slovenia, we also emphasized the limitations or assumptions taken into account by individual authors.
In the computational part of the thesis, the end bearing capacity is calculated according to selected authors for different pile dimensions and different soil characteristics. Some results of static and dynamic load tests for piles in cohesionless soil have been collected, for which end bearing capacity has been calculated using the approaches chosen and compared with results of load tests.
