Evaluation of methods for the stabilization of rocky slopes and slopes with a time-cost reduction approach (case study: ABALI slopes)

The Slops on the highway roads connect the road with the environment and are in fact a kind of cutaway that causes the natural stability and balance of the slopes and can cause landslide and drift in the slopes of the excavation or embankment. There are various methods for slope stability, which, according to the region conditions and requirements, one of them is used to stabilize the slope. In these studies, various ways of stabilizing the slope on the Abaleh road have been investigated in terms of cost and execution time. According to field studies, dangerous roads have been detected on this road and in the long run about 1 km from the road, which is actually the most dangerous part of the road according to road accident statistics. To conduct studies. The methods used in this case study are: reinforced concrete walls, nailing, the use of Gabion and the use of geocell. In these studies, the use of vegetation method was also investigated. Due to the impossibility of using this method on the slope, the model was not developed in MSP software. The results of the studies showed that, among the methods studied, Nailing as the best option and reinforced concrete wall is considered as the most cost-effective and time-consuming option for stabilizing the slope.
