Diseño de una obra de mitigación para la inestabilidad del terreno ubicado en el Km 1,5 de la vía Loja Zamora

Abstract

Abstract: The main objective of this work is to propose a stabilization model for the hillslope movement at kilometer 1.5 of the Loja-Zamora road, in the San Cayetano sector. This requires fieldwork involving topographic surveying, geological mapping, electrical resistivity tomography (ERT) testing, and laboratory tests to obtain the physical and mechanical parameters of the soil. This information is used to generate a geometric model with geotechnical parameters, which are used to generate a stability model using Slide 6.0 software. The resulting safety factor is FS=0.36, indicating that the hillslope movement is highly unstable due to the triggering factor associated with water seepage from higher elevations, which flows into the ground through pipes and drains in poor condition. There is oversaturation of the soil, causing ground displacement and subsidence of the road structure. To control the problem, deep trench subdrains are needed to control groundwater, reduce pore pressure, and lower the water table.
