One of the critical challenges in civil engineering is ensuring the stability of soil and rock masses, especially in roadway projects where the risks of landslides pose significant threats to the safety and continuity of transportation, trade, and tourism. This study focuses on stabilizing a fractured rock mass located at kilometer 126+240 of the road connecting Ticaco and Candarave in the Tacna region, Peru, a zone of high seismic activity. To address this issue, comprehensive field studies were conducted, including topographic surveys, rock mass classification, and sampling for further analysis. The analytical process involved modeling of discontinuities and a detailed kinematic analysis to classify and evaluate slope stability under static and pseudo-static seismic loads, emphasizing dominant discontinuity families. The results indicated that the rock slope, classified as Class V (Very Poor) by RMR and as Class IV (Poor and Unstable) by SMR, exhibited high structural vulnerability. Kinematic analysis identified planar failures with a 100% probability in the dominant family (66°/183°), 75% probability of toppling failures, and 41.09% probability of wedge failures. The initial Safety Factor (SF) under static load was 1.139 and 0.896 for pseudo-static load, both below the minimum required values of 1.50 and 1.25, respectively. By implementing 9, 12, and 15-meter self-drilling anchors at an inclination of -15° to the horizontal, the SF was increased to 1.743 under static conditions and 1.260 under pseudo-static conditions, achieving a substantial improvement in slope stability. This method proved effective in mitigating risks within the study area
