Rock Slope Stability: Comparison of Geogrid Box Method with Conventional Reinforcement Methods

This research sets out to review critically the current slope stability methods including geometry modification, rock bolt and wire mesh and to offer geogid box method as an alternative toconventional rock slope stability methods. Achieving the objectives of this research, the limit equilibrium (LE) and finite element (FE) analysis were conducted to predict the response of rock slopes to a broad range of possible scenarios, namely dry, half-saturated and saturated states; as wellas, static, quasi-static and dynamic conditions. The results indicate that the factors of safety obtainedthrough the geogrid box method are higher than those obtained through conventional reinforcement methods.
