This study presents an integrated geotechnical and geomatic approach for the stabilization of an active urban slope in the Av. Integración Barrial de Loja, Ecuador. The area, characterized by mass movements due to erosion and water infiltration into silty soils, represents a critical risk to road infrastructure and adjacent properties. The methodology included a precision topographic survey with Trimble R8 differential GPS, the excavation of two pits, and detailed laboratory tests (granulometry, Atterberg limits, and UU triaxial compression with remodeled specimens). These analyses allowed to characterize the predominant silts with a cohesion of 0.21 kg/cm2 and an internal friction angle of 30.00°. Stability modeling, executed in the Slope software using the Morgenstern-Price method, revealed initial safety factors below 1.25. As a mitigation solution, a 4.0 m high reinforced concrete cantilever wall was designed, complemented with crest ditches, 0.60 m wide × 0.40 m deep, for surface water control. The implementation of these measures projects a significant increase in safety factors, exceeding 1.50, which confirms the technical and economic feasibility of the proposal for risk management in urban slopes.
