N2 - Landslides in southern Peru are primarily caused by water saturation due to precipitation. Detailed geotechnical studies have identified parameters of soil layers, such as peat bog, gravel with fine sand, colluvial deposits, weathered slate, and fractured bedrock. These elements generate seepage and compromise slope stability. This research proposes the installation of horizontal drains along the slope to capture the seepage flow, using Slide 6.0 software and finite difference modeling technique. Different scenarios, both static and seismic, were conducted to evaluate the factor of safety. The results revealed that without drain installation, the factor of safety was 1.34 in the static scenario and 0.95 in the seismic scenario. However, by implementing the drains, stability significantly improved, with a factor of safety of 1.512 in the static scenario and 1.209 in the seismic scenario. In conclusion, the analysis of the results supports the effectiveness of installing drains along the slope to ensure stability in both static and dynamic conditions. This will help mitigate landslides and provide safer and more reliable protection for infrastructure and surrounding areas.
