Abstract
The design of axially loaded piles in non-cohesive soils is usually based on the β-approach. Recently, alternative CPT-based approaches have been developed by different research groups. However, in general the different approaches give different results, and it is not clear which approach is the best suited, i.e. most realistic, for special conditions. For the conditions of offshore wind energy foundations in the North Sea and with regard to tensile axial loading, a parametric study was carried out to ascertain the differences in pile capacity between the different approaches. It was found that in most cases the β-approach yields smaller pile capacities than the new CPT-based approaches. However, a calibration of the CPT-based methods for the considered conditions of piles with large diameter in dense to very dense sand has not yet been carried out. The new methods must therefore be applied with due caution until verified by experiments or sufficient experience.
