TERRACING SLOPE STABILITY ANALYSIS USING BIO-ENGINEERING SOIL REINFORCEMENT WITH 3D MODEL APPROACH

: Landslides can occur on natural slopes as well as on artificial slopes due to cliff cutting or embankment construction. Management of landslides on the slopes can be done by means of changes in geometry through the implementation of terraces or strengthening of the slopes. One method of strengthening the slope is with soil bio-engineering, whereby vegetation such as vetiver plants are grown. Vetiver roots increase the cohesion value in the soil and in addition to retaining the force on the slopes, the roots are able to penetrate the soil layer up to 3 meters. This does not take time as even at the age of one month, the roots of this plant grow as much as 0.5 meters and, after every 2 months, increase by 0.5 meters. The terrace system on the slope is able to increase the safety factor value by 21% and when the terrace is strengthened by vetiver roots, which are 3 meters deep, it is able to increase the safety factor value by 49%. The more the slope is strengthened by the vetiver root, the greater the percentage increase in the safety factor value against landslides.
