Abstract
The aim of this research was to evaluate the danger due to slope instability in the Section km 770 +617- km 771+706 of the PE-3S route, Abancay, Apurímac region. In this study, five slopes were evaluated under the affected conditions. Slope inventory was used. The Danger Stratigraphy (CENEPRED, 2014) was carried out; the soils of the slopes were classified according to the Unified Soil Classification System (SUCS). ArcGis software was used to determine the coordinates of the pits and GEO 5, to evaluate the stability of the slopes. Sub-Section 1 to Sub-Section 5 were classified respectively as argillaceous gravel (GC), low plasticity clay (CL) and silty gravel (CL-GM). All sub-sections evaluated showed a very high level of danger and the safety factors for each corresponding sub-section showed that there is a greater probability of landslides (minimum value), which determines the instability of the entire sub-section under study.
