This thesis analyzes and compares the two most common retaining wall systems in Peru: gabion walls and reinforced soil walls with Terramesh system. For this comparison, the project “improvement of the Choropampa-Cospán road in the region of Cajamarca” was chosen, where there are three critical sections with problems of constant landslides and slope instability caused by slopes very pronounced that would be generated if no retaining walls were used. The design of gabion walls is done with ASD methodology (Allowable Stress Design), which works with allowable stress design and uses a single global safety factor; the Gawacwin program was used to do that design. The design of reinforced soil walls uses LRFD (Load and Resistance Factor Design) methodology, which works with a design by the required strength and uses a safety factor for loading and another safety factor for resistance; for this the MSEW program was used. Once both systems are designed, we proceeded to perform a technical comparative analysis with the most important features of each system at construction; and an economic comparative analysis using reference budget for each system, where we calculated the cost of the materials used, workers, earthwork and specific activities to be carried out. Once obtained the results, we look for comparative ratios that allow us to get the cost per square meter of each system and the cost per square meter of each height. At the end of the investigation we concluded that the walls of reinforced soil are more economical for heights over four meters, so in the sections one and two are recommended using gabion walls, while in the section three are recommended the construction of reinforced soil retaining wall.
