Análisis de los deslizamientos en la vía Loja Zamora abscisa 30+600 hasta 55+200, a partir de la integración lluvia, pendiente y formación geológica superficial

Abstract

The mass movements in the Loja - Zamora road have caused discomfort and insecurity in its users, in order to identify the areas most likely in mass movements and determined the rains critical for the occurrence of movements in the mass the project Analysis of landslides on the Loja - Zamora road abscissa 30 + 600 up to 55 + 200 was proposed, based on the information rain, slope and shallow geological formation, the analysis corresponds to the thresholds of precipitation and the preparation of a susceptibility map for the occurrence of mass movements. To determine the precipitation thresholds, the empirical method was used, and to elaborate the susceptibility map, the heuristic method was used with the multicriteria analysis of SAATY. The variables considered are geology, slope, soil cover and precipitation. The results indicate that the previous accumulated rain is the trigger in the occurrence of mass movements. From the multicriteria analysis, geology is the determining factor with the greatest incidence for the occurrence of mass movements.
