Numerical Modelling Techniques for Stability Analysis of Slopes Reinforced with Shallow Roots

It is well recognised that plant vegetation and roots are capable of improving the shear strength hillslopes by reinforcing soil resistance. Several key factors influencing level slope reinforcement include root geometry, orientation strength. To assess mechanical performance vegetated slopes using numerical methods, structures can be represented beam pile elements to mirror behaviour. In contrast, modelled indirectly through a cohesion factor, supplying additional surrounding zone. this paper, correlations between these two methods presented, highlighting applicability each technique based on various characteristics. Three types geometries consisting primary tap root, secondary zone main branching process. The results finite element analysis demonstrate variation in factor safety for both with set modelling approaches. A series stability charts presented method, quantifying effects characteristics reinforcement.
