Análisis de la incidencia de las precipitaciones acumuladas en el comportamiento mecánico de los suelos que componen una ladera. Caso de estudio vía Loja - Malacatos

Abstract

Abstract: Landslides represent a danger which is important to analyze since the lives of living beings and the infrastructure as communication routes are at stake. Based on the research analyzed, precipitation is a very important factor to take into account since several authors relate it directly to landslides. However, the studies carried out in the city of Loja are minimal. Therefore, it has been proposed to determine the incidence of precipitation in movement of slopes in mountain roads. To achieve this, a hillside was selected and 9 control points were obtained. In each of these, data was obtained on moisture content, infiltration, mass movement and precipitation. With the help of a software, safety factors were obtained at different dates for each profile. The main results show that profile 2 (composed of low plasticity silt and silty sand) obtains the most critical safety factor as it was 0.64. The point with the highest travel speed was point 6 with a speed of 0.091 meters/month. This research will serve to confirm the existence of a direct relationship between precipitation and slippage. In addition, based on this, mitigation measures could be proposed for the landslide posed on the slope.
