The present investigation had as objective to analyze the stability of the slope located in the progressive 23+710; of the Yaurisque - Ranraccasa Highway, Paruro and plan a stabilization proposal. For which, after having obtained information on the physical-mechanical properties of the soils and topographic characteristics of the slope, the factor of safety (FS) and its interpretation were determined, from this a stabilization system was proposed, using the methodology of limit equilibrium through analysis and modeling in Geo5 software. To achieve the objective of this thesis work, firstly, the recognition of the study area, the inspection and identification of the most critical slope was carried out. With the information obtained, a topographic survey was carried out in order to know the morphological characteristics of the land surface and establish the analysis sections. Subsequently, the vertical electrical sounding (SEV) test was carried out, considering the most critical areas of the slope defined above, to, through the electrical properties of the soil, know the resistivity distribution of the soil, thus determining the geoelectric stratification of the terrain, knowing bedrock and identify the water table; With the interpretation of the above, we proceeded to extract soil samples from the pits located from the previous information, with the purpose of knowing the physical-mechanical properties of the soils present in the study area, through the execution of tests of laboratory and in situ; tests such as: Triaxial compression test of the Unconsolidated Undrained (UU) type, Granulometric Analysis by sieving, Liquid Limit, Plastic Limit, Natural Moisture Content, Infiltration Rate Test (Porchet), Field Density by the Sand cone, Light Dynamic Penetrometer (DPL) test and specific gravity using the water pycnometer, which allowed us to determine some important soil parameters, such as: Soil classification, specific weight, Angle of internal friction, cohesion, etc. ., these parameters were essential for obtaining the safety factor (FS) and slope stability analysis, using the limit equilibrium methodology which is based on the laws of statics to determine the equilibrium state of a mass of potentially unstable terrain where resisting and destabilizing forces are uniformly along the failure surface of the slope; through the use of Geo5 software in its presentation "Slope Stability", which is a software that includes limit equilibrium methods. Finally, a maximum value of the safety factor (FS) for the analysis sections of 1.35 was obtained, thus being determined; that the studied slope is unstable according to the minimum safety factor (FS) of 1.5 required by the national regulation CE020 "Stabilization of soils and slopes". Therefore, a stabilization system was proposed with the modification of the slope section by reducing the slope (lowering the slope), incorporating retaining walls (gabions) and a drainage system, to later carry out its corresponding analysis, achieving achieve a minimum safety factor (FS) of 1.50, which exceeds the minimum safety factor required by national regulation CE020 "Stabilization of soils and slopes", thus guaranteeing the stability of the slope.
