САЖЕТАК / ABSTRACT:
The paper presents a methodology for quality management in pile testing and analyzes the results of pile tests for wind turbine foundations. Quality control was carried out in accordance with ISO/IEC 17025 for Static Load Tests (SLT) and Dynamic Load Tests (DLT), alongside the introduction of a new technical document – the Pile Testing Project, which defines, implements, and supervises the entire testing process. Tests were performed using both reaction and autonomous hydraulic loading systems. The study found that most DLT results fall within the mean value and standard deviation range, noting that DLTs were performed in foundation pits on service piles, whereas SLTs were conducted outside the pits on test piles.
