Soil nailing is an earth retaining technique used to stabilise existing slopes and support excavations. The stability post construction can change due to variation in groundwater, resulting in a reduction of effective stress in the soil. Nine centrifuge model experiments were performed investigating the influence of reducing the effective stress within the model by water inundation. The models tested were 1/10th scale. The full-scale prototype excavation was a three metre high cutting with a slope angle of 70°. The corresponding forces developed in the nails and displacements developed are assessed.
