Análisis de la estabilidad del talud ubicado en la vía lateral de paso Ángel Felicisimo Rojas, a la altura de la laguna de Punzara en las coordenadas 699854.82; 9552784.16

Abstract

Abstract: Extensive investigation in the study area has revealed significant slope instability, which poses a risk to civil works construction and local safety. Geological, geomorphological, lithological and topographical analyses highlight the terrain's predisposition to landslides. The presence of the Quillollaco Formation, with conglomerates, silty-clayey sand and sandstone, contributes to the lack of soil cohesion. The topographic analysis shows steep slopes and a medium hilly relief, potential triggers for landslides. Evaluation of the mechanical properties reveals that the slope soils are prone to instability due to low friction angles and high cohesions. Although conglomerate soil is more stable, it requires careful engineering considerations. The classification of soils according to AASHTO and SUCS standards highlights the variability of properties in the area, impacting the bearing capacity and strength of structures. In addition, it is corroborated by the geophysical survey, which together indicate the same type of classified soil. Finally, the soil profiles reveal instability under static and dynamic loads, with safety factors below recommended standards.
