Geodinámica del movimiento de ladera en calle “Gonzalo Pizarro” de la ciudad de “Zaruma” provincia de “El Oro”, mediante la aplicación de métodos geofísicos y geodésicos

Abstract

The present investigation is focused in the study and problematic related to the slope movement of the street "Gonzalo Pizarro" of the city of Zaruma. It is convenient to apply multiple methods, integrating new technologies such as 3D laser scanner, differential GPS, geophysics and geotechnical methods, in order to obtain more effective results that allow us to know the correct reality of the study area. According to the differential GPS ranges, the movement moves at relatively slow speeds, which is related to the displacement values generated by the difference of elevations made with 3D laser scanner; the profiles of electrical resistivity tomography show really high values, attributed to glass tuffs typical of the study area, also positive anomalies attributed to galleries of mining works are observed; the geotechnical tests show altered residual soils of the main rock, which can be attributed to the instability of the terrain; all these obtained data allow us to define the slope movement as a creep, with possible subsidence caused by the mining works that exist under the study area.
