Análisis de deformaciones verticales de un movimiento de ladera mediante observaciones GPS y nivelación geométrica de alta precisión

Abstract

The current research determine the degree of precision of vertical deformations through two methods of monitoring with a differential and electronic level GPS, they were made in a simultaneously way and in the same periods of time. In order to carry out this research, a control network was implanted in the zone which has 36 points placed on hillside in the Chontacruz neighborhood in the southwestern in the Loja city and it was chosen this hillside because it shows clear evidences of slides in active state. For monitoring, 10 measures were made in a period of 7 months calendar between June to December in 2016. The results of this research have allowed to confirm that the method of leveling of high precision is the most recommendable due to it has minor dispersion in data with a value of 0.017 ± 0.001 m in comparison with the GPS that was 0.020 ± 0.002 m.
