Modelling the effect of vegetation on slope stability

Abstract

ABSTRACT This thesis seeks to focus on the aspect of vegetation in improving the stability of slopes through modelling and analysis. For this purpose, cross-sectional geometries of the slopes and the effects of various plant species on the mechanical and hydrological response of the slopes are considered by employing Geostudio software and 2D-Plaxis software. This arises through increased cohesiveness and strength offered by roots in the stability of the soil and consequently, the factor of safety thus reducing the disaster of landslides. The results of the work thus support the applicability of vegetation as a cheap and environmentally friendly solution to slope stabilization and vegetation impacts on the mechanical properties of soil and enhancement of infiltration. Suggestions for further research are the investigations of the fourteen species with respect to root cohesion and the combination of vegetarian technologies with standard engineering to create strong slope management plans.
