Análisis de la incidencia del contenido de humedad de los suelos en el movimiento de laderas asociados a infraestructuras de carreteras, mediante métodos estadísticos

Abstract

The purpose of this study was to determine, by means of a statistical method, the effect of soil moisture content on slope movement, associated with the Neighborhood Integration Road in the Northwest Sector of Loja. In the study area, measuring points were installed to measure moisture content for six months. Soil samples were extracted to obtain their physical and mechanical properties. In addition, it was generated by the geostatistical method, ordinary Kriging, maps of variability of moisture content to observe and analyze the spatial distribution of humidity. The results indicated that clayey soils with high plasticity and loamy sand predominate in the site. The type of movement that occurred was rotational slip. The areas with clay sand in the upper layers had a lower moisture content than in the deeper ones where high plasticity clay was found, so it is assumed that the sand allowed a rapid infiltration of the water and the clay was saturated, triggering the slope movements.
