Abstract

A new method of estimating the static capacity of driven piles in silica sand, referred to as the Unified method, is included in the forthcoming 2022 edition of ISO-19901-4 and replaces the four CPT methods recommended in ISO-19901-4 (2016). This paper investigates the application of this method to the prediction of driving resistance of pipe piles using seven high quality case histories involving piles with diameters in the range 340mm to 4.2m. It is shown that the Unified method, adapted to enable estimation of the static resistance to driving (SRD), can lead to considerably improved predictions of driving resistance compared to an existing popular method used for SRD determination. Further refinements to the proposed formulation, referred to as UniSand-SRD, will be possible on examination of additional high quality case histories.
