Selected modeling problems of monopile foundations used in the energy industry

Abstract

The paper presents selected practical aspects of the construction of monopile foundations used in the onshore power sector and analysis the effect of these solutions on the design of such structures. The basis for the evaluation of load capacity of such foundations was briefly discussed and the key factors that determine the ability to transfer loads from the structure to the ground were indicated. The main problem presented in the paper was to assess the impact of the reinforced concrete stay-in- place formwork piles built using the well technology. The considerations were supplemented with a computational example illustrating the thesis presented in the paper. A positive effect of prefabricated formwork rings on the load capacity of the foundation was demonstrated.
