STABILITY ANALYSIS OF A ROCK SLOPE – ARAPA

Objective: To evaluate the geomechanical stability of a slope located in the "Lajas de Arapa" sector, Arapa district, Azángaro province, Puno region, using classifications such as RMR, SMR and laboratory tests to determine the safety conditions of the slope. Met-hods: field measurements were carried out in 10 geomechanical stations, laboratory tests such as point load tests, Til Tes and uniaxial compression (UCS), and specialized software (DIPS and RocPlane) were used for stability analysis and determination of the safety fac-tor (FS). Results: The FS obtained was 0.835, indicating an unstable slope condition. The geomechanical parameters show low cohesion and friction angle of 30°. In addition, it was identified that sedimentary rocks have high susceptibility to landslides due to their structure and silt content. Conclusion: the slope requires stabilization measures, such as modification of its geometry, adequate drainage and structural reinforcement, to guarantee road safety and prevent landslides.
