Abstract
The effect of using geogrid boxes as a new approach for reinforcement of rock slopes (with a case study at rock slope perched along km 11 + 060 of Mianeh–Ardabil railway track) was investigated. The limit equilibrium (LE) and finite element (FE) analysis were conducted to predict the response of the slope to a broad range of possible conditions, namely dry, half saturated, and saturated states as well as static and quasi-static conditions. The objective is to contribute towards the establishment of best practice in the design and construction of engineered slopes. Various design considerations were developed to investigate the effect of varying height and width of geogrid boxes on the factor of safety. The LE and FE based methods were compared based on the factor of safety. The results demonstrated that considering the design consideration, installing geogrids yields increasing the stability of rock slope.
