Análisis de la variación del factor de seguridad mediante el método de elementos finitos aplicados a laderas ubicadas en el sector norte de la ciudad de Loja en función de la surgencia de suelos cuaternarios

Abstract

The watershed of Loja presents several problems related to unstable slopes that affect its normal functioning and represent a risk for the existing population around it and the road infrastructure. The present work analyzes the stability of the slopes Km 2 + 900 and Km 4 + 500 of the Loja - Catamayo road in which different factors triggered a mass movement. A modeling was done by means of software phase, analyzing as the primary triggering factor the water. Applying the finite element method MEF, the analysis of the layers of the slides and the fault zones are performed, applying the shear reduction method. It is modeled according to the original physical and mechanical properties of the slope and the water table, to propose the mitigation measure to each slope and to evaluate the safety factors and values of displacements obtained.
