Slope instability in railway infrastructure represents a technical problem associated with rainfall, surface runoff, weathering, erosion, and progressive degradation of exposed soil or rock masses. This study applies the Analytic Hierarchy Process (AHP) to prioritize slope stabilization alternatives using four evaluation criteria: geological conditions, slope geometry, instability or risk level, and hydraulic conditions. Four alternatives were assessed: geomat with hydroseeding, shotcrete with previous surface trimming, a mixed system with geomat, mesh and anchors, and an integral stabilization system with drainage and structural treatment. The criteria comparison matrix showed acceptable consistency, with a consistency ratio of 0.044. Results indicated that the integral stabilization system obtained the highest global priority, with 51.2 %, followed by shotcrete, the mixed system, and geomat with hydroseeding. The proposed approach provides a structured decision-support tool for selecting technically justified slope stabilization measures.

Selección multicriterio de alternativas de estabilización de taludes para infraestructura ferroviaria mediante el Proceso Analítico Jerárquico
Resumen:
La inestabilidad de taludes en la infraestructura ferroviaria representa un problema técnico asociado con las precipitaciones, la escorrentía superficial, la meteorización, la erosión y la degradación progresiva de masas de suelo o roca expuestas. Este estudio aplica el Proceso Analítico Jerárquico (AHP) para priorizar alternativas de estabilización de taludes mediante cuatro criterios de evaluación: condiciones geológicas, geometría del talud, nivel de inestabilidad o riesgo y condiciones hidráulicas.
Se evaluaron cuatro alternativas: geomanta con hidrosiembra, concreto lanzado con perfilado previo de la superficie, un sistema mixto con geomanta, malla y anclajes, y un sistema integral de estabilización con drenaje y tratamiento estructural. La matriz de comparación de criterios mostró una consistencia aceptable, con una razón de consistencia de 0,044.
Los resultados indicaron que el sistema integral de estabilización obtuvo la mayor prioridad global, con un 51,2 %, seguido del concreto lanzado, el sistema mixto y la geomanta con hidrosiembra. El enfoque propuesto proporciona una herramienta estructurada de apoyo a la toma de decisiones para seleccionar medidas de estabilización de taludes técnicamente justificadas.
