| metadata.dc.description.abstractenglish: | The Chichaca Tunnel was handcrafted by the residents of Chantaco and Chuquibamba in 11 the Catamayo Canton of Loja Province, Ecuador. Its construction began in 1936, took nearly 20 years, 12 and was completed using only hand tools and blasting techniques. The tunnel spans 62 meters and 13 serves as a crucial route for the region's residents. Despite its stability to date, concerns persist re- 14 garding its safety due to the lack of geotechnical investigations. This study addresses these concerns 15 by employing advanced photogrammetric reconstruction techniques, specifically Structure from 16 Motion (SfM), to analyze the tunnel's discontinuities and identify potential structural vulnerabili- 17 ties. Additionally, a stability analysis will be conducted using Barton's Q-System for geomechanical 18 classification, complemented by wedge failure analysis. By focusing on the tunnel portals and mid- 19 section, this research aims to provide a comprehensive assessment of the Chichaca Tunnel's stability 20 and safety. |
