This paper presents the characteristics of the new geotechnical centrifuge of the Escuela Colombiana de Ingeniería Julio Garavito, including the installed capacities, future applications, and possibilities that offer the new centrifuge as an important tool for teaching and learning in geotechnics. This centrifuge has a radio of 610mm and a maximum acceleration of 200 gravities. A very complete acquisition system with a capacity of 12 sensors to measure different properties is installed. Also, the centrifuge has five oedometric consolidometers as a complementary tool to prepared fine soils in the construction boxes. The possibilities in teaching soil mechanics and applied soil mechanics using the new centrifuge are multiple and are based on the visualization of failure surfaces and deformations produced by different geotechnical structures.

The purpose of this study was to explore the influence of vegetation on the stability of clayey slopes. Physical models with varying layer depths reinforced with roots were performed in a geotechnical centrifuge. The soil reinforced with vegetation was simulated with a mixture of clay and fiberglass which present similar shear strength properties. Displacement vectors of the physical models are obtained using the Particle Image Velocimetry (PIV). The computed resultant displacements showed that the slip surface varied with respect the root depth. Additionally, numerical models of the tests in centrifuge were made using finite elements and Bishop’s method. The results obtained also show that the deeper the roots, the deeper the sliding surface. The slip surface moves from a depth of the slope toe (slope without reinforcement) to a depth close to twice the height of the slope. Regarding the factor of safety, it varies from a value of 0.7 for slopes without vegetation to 1.19 for a root depth of three meters. Moreover, the factor of safety increases as root depth increases.
