The effects of soil nonlinearity and pile–soil separation were accounted for in the analysis by employing a weak boundary zone around the piles in the analytical model. The experimental results show that the dynamic behaviour of helical piles is essentially the same ...

This paper presents the comparison between the full-scale vertical vibration response of a 9.0 m large-capacity single-helix pile and a driven steel pile of similar length, in order to qualify and quantify the large-capacity helical piles and driven piles' dynamic performance. The test piles ...

[25] estimated the frictional resistance of driven piles using a four-layer ANN. Moayedi and Hayati [26] applied a feed-forward ANN to the information of bored piles for forecasting load–settlement responses. Their proposed model achieved an accuracy greater than 99% (in terms of the R-...
