Modelling of mechanical roots on slope stability

Root system mechanical reinforcement through root-soil cohesion on slope stability is important. However, the root of <em>Tectona grandis</em>, <em>Maesopsis eminii</em>, and shrubs (<em>Chromolaena odorata</em>) rarely studied modelled. This study aimed to model effect vegetation cohesion, namely teak (<em>Tectona grandis</em>), odorata</em>). The was conducted in a simultaneous landslide January 1, 2020, that dominantly occurred vegetated slopes Sukajaya District, Bogor Regency, West Java. Wu model's (<em>C<sub>R</sub></em>) modelled using modified Bishop model. modelling used data from field laboratory-measured. found presence increases stability's factor safety (FOS). young <em>Maesopsiss eminii</em> produces largest FOS compared shrubs, teak, old eminii</em>. function <em>C<sub>R</sub></em> effective zone depth. highest total with 0.398 kPa, followed by eminii, </em>and<em> </em>old 0.202 0.191 0.087 respectively. shrub were 500, 230, 140, 66 cm,
