Centrifuge modelling of slope stabilisation using a discrete pile row

Abstract

Discrete pile rows are an established technique for improving the stability of infrastructure slopes. However, the impact of pile spacing along the row is not clearly understood from a current design perspective in terms of the ultimate interaction capacity. A series of geotechnical centrifuge model tests were undertaken with the upper layer of a slope tending to fail and interact with a discrete pile row. The results were interpreted to clarify the effects of pile row interaction with the slope, and verify results from other recent numerical studies.
