Development of the UWA-05 design method for open and closed ended driven piles in siliceous sand

This paper draws upon recent research findings to propose a new CPT qc based design method for predicting axial capacity of open and closed ended driven piles in siliceous sands. The method incorporates various factors that are acknowledged to have a controlling influence on pile capacity including (i) the effects of soil displacement during installation, (ii) friction fatigue, (iii) sand-pile interface friction angle, (iv) changes in radial stress during loading, and (v) the influence of loading direction.
