ABSTRACT
Pile foundations are an important part of geotechnical engineering because they are a proper solution to support high-significance structures, structures for which shallow foundation is not possible. The infrastructure cost can vary between 5% and 20% of the total cost, so that it is necessary a more accurate design to achieve efficiency both in terms of performance and operational safety and also in terms of the economy.
The paper presents an analysis of the behavior of large diameter piles under axial loads. The aim is to compare the relationship between the applied load and the registered settlements in correlation with the contact between the pile shaft and the surrounding soil. There was performed a static load test on a pile and the obtained results were analyzed from the point of view of the variation of the shear resistance parameters. The theoretical analysis of the pile behavior was conducted using the computer code Geostru-MP, which allows to determine the influence of the shear resistance parameters of the soil on the bearing capacity of the piles.
