Geodesia aplicada al monitoreo de movimientos de ladera y la influencia de la precipitación en la ciudadela Daniel Álvarez Loja, durante el período 2024

Abstract

Abstract: The purpose of this research is to monitor slope movements at the Daniel Álvarez citadel, located in Loja, Ecuador, using advanced geodetic techniques, which combine the use of a Total Station, Differential GPS (DPS), and Crack Meters to record and analyze displacements, as well as the evolution of fissures and/or cracks in buildings. The methodology began with the delimitation of three study zones, where different monitoring approaches were implemented depending on the terrain conditions. In Zones A and B, fixed and auxiliary points were established using Differential GPS technology, complemented by mobile points monitored biweekly using the Total Station. In Zone C, due to physical constraints, only Crack Meters were used, with monthly measurements of structural cracks. Additionally, meteorological data were collected to correlate rainfall events with displacements. The results in Zone A averaged a ground movement of 3.81 mm, while in Zone B, the movement reached 5.59 mm. Finally, in Zone C, crack development of up to 2.24 mm was evident.
