Methodologies based on metaheuristic algorithms such as particle swarm optimization, harmony search algorithm, and teaching-learning-based optimization are proposed for optimum design of reinforced concrete cantilever retaining walls. The objective function of optimization is to find a design providing minimum cost, including material and construction costs. For this purpose, the best combination of 11 design variables (heel and toe projections, stem thickness at the top and bottom of a wall, slab thickness and rebar diameters, and spacing between the bars) that satisfy 29 design constraints including stability (overturning, sliding, and bearing) and reinforced concrete design of the wall are searched during the optimization process. The rules of ACI 318 14 (building code requirements for structural concrete) are used for the reinforced concrete design. In order to determine the strengths and weaknesses of algorithms, several different cases are investigated. As conclusions, some suggestions have been obtained that will lead to future work in this field.

Reinforced retaining walls were used on the overpasses of the Central Ring Road. To reduce the sedimentation of the base of these walls, to reduce the time of consolidation of the base, the transformation of soil properties by reinforcing vibro stone columns was used. In order to obtain an optimal result for the transformation of the properties of the base soils, increasing the reliability of the reinforced structures, comparative calculations were carried out with the variation of the parameters of the reinforcing elements. The method of quality control of the device vibro stone columns is improved.
