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.

 In the present paper, lessons are learnt from ant society so that humankind can optimize his engineering issues. As an example of such issues, a reinforced concrete retaining wall for which the application of optimization can reduce the costs involved is considered. Traditional design procedure for reinforced concrete retaining walls is unable to design an optimized wall unless a large trial effort is undertaken. This paper introduces a learning procedure from ants, which is a general search technique for the solution of difficult combinatorial problems with its theoretical roots based on the foraging behavior of ants. This methodology arrives at an optimal design for concrete retaining walls due to its capability to explore and exploit the solution space effectively. The basis of analysis in this paper is to determine the minimum weight and costs in the design of concrete retaining walls following a computation of lateral total thrust on the wall due to backfill pressures, bearing capacity consideration, settlement analysis, stability analysis, and application of design of reinforced concrete principles. The results clearly indicate that ant colony can educate engineers comprehensively to reach a minimum cost justified retaining wall through an optimization approach.
