Monitoreo integral del movimiento en masa del sector la urna (vía antigua a Catamayo) de la ciudad de Loja utilizando equipos gnss de bajo costo: caso polígono 2

Abstract

Abstract:The main objective of this study, entitled Comprehensive Monitoring of Mass Movement in the La Urna Sector (Vía Antigua a Catamayo) in the City of Loja Using Low-Cost GNSS Equipment: Polygon 2 Case, is to determine and characterize mass movement in the aforementioned sector using low-cost GNSS technology. The methodology implemented included the collection of bibliographic and field information, the determination of critical monitoring points, the installation of cement markers with wooden pins (Bmark), and the collection of geospatial data using Garmin GPSMAP 65S equipment. Three data collections were made on different dates to evaluate horizontal and vertical displacements, in addition to calculating movement speeds and directions. The results showed minimal displacements ranging from 0.02 m to 0.07 m in the horizontal component, and between 0.02 m and 0.06 m in the vertical component, with velocities of up to 0.13 cm/day. The predominant direction of movement was northwesterly (NW), suggesting an influence from the natural slope of the terrain and local lithology. Conditioning factors were identified, such as the presence of plastic and low-cohesion materials, as well as a deficient drainage system that contributes to soil oversaturation during rainfall.
