Inventario de deslizamientos e infraestructura vial de la vía Loja Saraguro

Abstract

Abstract:Keeping the road infrastructure through proper management and maintenance, ensures its proper functioning and extend its useful life, so the first step is to know the current status of its components. The following work carries out a road inventory of the infrastructure and landslide elements in the Loja-Saraguro road, in order to obtain detailed thematic maps using geographic information systems to register them in an up-to-date database. The methodology used is a combination of techniques for extracting field data with georeferencing using GPS; furthermore, the characterization and analysis of the stability of a critical slip was made by the method of limit equilibrium to find its safety factor. It is concluded that in the study section regarding “obras de arte”, a total of 273 culverts, 2 bridges and 10 walls were identified and evaluated; 773 vertical signs were recorded and 9 landslides were identified, of which 3 are active. From the analyzed slide a stabilization measure was proposed by drainage.
