Modelling Root-reinforced Soils with Nor-Sand
Abstract There has been much effort in the past years to characterise the mechanical behaviour of root-reinforced soils, both in terms of strengths and stiffness. This paper presents a simple extension of bounding surface model called Nor-Sand, which captures the progressive activation of the roots in the frame of continuum mechanics. This is achieved by considering the changes in the yield and the bounding surfaces, which influence the hardening and softening rates as well as the predicted peak strength. The model is implemented in the finite element software Abaqus and used to simulate element tests. The macroscopic modelling approach facilitates the modelling of large-scale problems such as the erosion of dunes, which is of importance for coastal regions.
