Due to the landslides that occurred on the Pucruchacra hill, a fact that affected the Carretera Central, the most important road in the country, the State, through the company Dobac S.A., implemented a gabion system with benches in that area. The present investigation proposes that a drainage drilling system with anchors can provide greater stability to the slope of the Pucruchacra hill, than the existing system. Therefore, to demonstrate the hypothesis, geotechnical and topographic information was required, which was obtained from previously done studies. This information was used in the SEEP/W and SLOPE/W software to make modeling in order to determine the critical section -the one with the lowest safety factor- of the studied section. In this critical section, the modeling of both mentioned systems were made to later be compared and determine which one guarantees greater stability to the slope. The drainage drilling system with anchors was modeled with one, two and three rows of drains, to know the behavior of the slope. The drainage results show that there is no major difference between the gabion system with benches and the drainage drilling system with anchors, the latter having three rows of drains. However, a positive trend in the safety factor was evidenced as the rows of drains increased, so it is likely that the safety factor will continue to increase with more rows. On the other hand, despite the similarity of the safety factors between both systems, it is considered that the drainage drilling system with anchors is a better alternative, since, due to its characteristics, it does not need large movements of land, therefore, the duration and cost of the project would be less; another feature in favor is the non-need for maintenance, since these drains, due to the type of material they have, are not clogged.
