Geotextile is being increasingly used for slope reinforcement. The failure mechanisms are important to make safe and economic design of geotextile reinforced slopes. Centrifuge modelling is a powerful tool for physical modelling of reinforced slopes and offers the advantage to observe the failure mechanisms. In this paper, we report a series of model tests on geotextile reinforced slope with three different slope inclinations of 65°, 75°, and 85° in a geotechnical centrifuge. The aim is to identify the possible failure mechanisms. All reinforced slope models have the same height of 270mm. Dry sand was used in the experiments. The model box was subjected to increasing centrifugal acceleration until failure occurred. Photographs of the slope models were taken in flight with a digital camera and the deformations were evaluated with Particle Image Velocimetry (PIV).
