Discrete passive piles for infrastructure slope stabilization
Discrete passive piles for infrastructure slope stabilization
Discrete piles are increasingly being used to stabilise infrastructure earthwork slopes such as road and railway embankments and cuttings. Historically, there have been a number of uncertainties relating to how such piles behave. These include the maximum spacing at which such piles can be installed and still be effective, appropriate methods of analysis especially when there no obvious pre-existing failure surface, and the limiting lateral pile soil pressure especially in an effective stress analysis. This paper discusses these issues, with reference to geotechnical centrifuge tests, three dimensional finite element analyses, and field measurements over a period of years at a number of sites that reveal a variety of different pile-soil interaction behavioural modes.

Abstract
Discrete piles are increasingly being used to stabilise infrastructure earthwork slopes such as road and railway embankments and cuttings. Historically, there have been a number of uncertainties relating to how such piles behave. These include the maximum spacing at which such piles can be installed and still be effective, appropriate methods of analysis especially when there no obvious pre-existing failure surface, and the limiting lateral pile soil pressure especially in an effective stress analysis. This paper discusses these issues, with reference to geotechnical centrifuge tests, three dimensional finite element analyses, and field measurements over a period of years at a number of sites that reveal a variety of different pile-soil interaction behavioural modes.
