Probabilistic Analyses of Root-Reinforced Slopes Using Monte Carlo Simulation

Among measures that are used to prevent the triggering of shallow landslides and for erosion control, root reinforcement has spread out widely as its contribution environmental sustainability is high. Although in recent years reliability-based design (RBD) been applied increasingly assessment slope stability address shortcomings deterministic approach (which does not consider geotechnical uncertainties explicitly), there still a lack application this method reinforcement. Plants characterised by high inherent uncertainty, making it necessary investigate level reliability these soil-bioengineering techniques. In context, determine whether or root-reinforced slopes designed according Eurocodes (that is, applying their statistical partial factors), providing satisfactory factors safety, may lead probability failure contrast, unacceptable, Authors carried several probabilistic analyses using Monte Carlo simulation (MCS). MCS was simplified Bishop Method modified bear pseudo-static forces representing earthquake loading mind. To take into account mechanical effect provided roots, an apparent cohesion added Mohr–Coulomb criterion. Results showed every configuration satisfies safety criterion acceptable levels reliability, evidence caused variability parameters.
