Aplicar la técnica GNSS al movimiento de laderas activas. Caso de estudio: Sector el Plateado

Abstract

Abstract: The objective of this work is to use GNSS techniques to measure the displacements of a hillside movement which is located in El Plateado sector of the city of Loja - Ecuador. A non-permanent control network composed of 25 points was established and through the fast static technique the coordinates were determined in 9 monitoring periods. After the processing of the GNSS data, the respective analysis was performed to determine the displacement vectors and the speed, determining that the slope movement has a slow movement according to the classification of slope movement according to Varnes, with a predominant direction towards the Northeast, likewise, the type of fault it presents is of the rotational type with clear evidence of activity at the level of the crown, body and foot of the slope. With the precipitation data and the characteristics of the soil, it is established that surface water influences the internal layers of soil constituted mostly of silt of low plasticity.
