Abstract

There are various conventional methods used to improve stability of slope and surface erosion. They all have merits and demerits, but the use of vegetation has many advantages such as root does not corrode, they are self repairing, regenerating and environmental friendly. This discipline has gained a global recognition for a long time and has been addressed as a new entity, “Ecological Engineering” which is defined as the design of sustainable ecosystem that integrates human society with its natural environment for the benefit of both. This paper considers the potential engineering influences of vegetation and how it can be characterized on site within a geotechnical framework for stability assessment. To gain more understanding on its soil root interaction and effects on slope stabilization, the mechanical and hydrological effect of vegetation would be combined and their overall effect on slope stabilization and slope stability analyses would be evaluated. The results obtained for the Vetiver Grass and Lime Tree will be considered. In overall the results show the considerable improvement in the slope stability by applying vegetation on finite slope depending to their location on slope. The results also indicate that Vetiver Grass can cause significant improvement in the slope stability compare to the Lime Tree even when it is located at the crest of slope due to its roots geometry and lower weight.
