Análisis del movimiento de taludes utilizando la técnica de fotogrametría terrestre, caso de estudio vía lateral de paso

Abstract

Abstract: Throughout history, the slide of slopes on roads has been a problem that endangers the safety of people, so the search for new methods that facilitate their monitoring is of great importance. This research aims to verify the effectiveness of terrestrial photogrammetry in the monitoring of slopes with different geometry. Three slopes located on the side passageway of the city of Loja were monitored. The monitoring process was carried out through a network of georeferenced control points located on the sides of the slopes. Here, various photogrammetric sweeps were used to capture photographs; however, the one that gave the best result at meeting accurate parameters in terrestrial photogrammetry was the longitudinal photogrammetric scanning. Furthermore, the data obtained in conjunction with the photographs was processed by using Structure from Motion (Sfm) technology. It generated digital elevation models (MDS) in which it was evidenced the presence of the type of erosion in the slopes according to the mechanical composition of soils. The results indicate that the method is effective, fast and low cost.
