Effects of Driving Sequence and Spacing on Displacement-Pile Capacity
AbstractThe installation sequence and spacing of displacement piles can influence the driving resistance (i.e., blow count) and associated capacity, however, engineers can rarely account for this effect in a direct manner. Increasing the availability of high-quality measurements of the effects of driving sequence and spacing to designers could help improve the understanding of production data and inform decisions mid-project. This paper presents some observations of pile driving resistance and pile capacity measured following an experimental program on the use of timber displacement piles in a well-characterized test site. Significant increases in pile capacity were observed as a function of decreased pile spacing depending on the order of installation. After correcting for the estimated residual loads, a fourfold difference in shaft capacity was observed between free-field and a pile in-filled at five pile head diameters.
