Estudio de la geodinámica superficial en la vía troncal amazónica en el tramo Tumbes - Gualaquiza.

Abstract

This research consists of making a map based on the Geodynamic land displacement in the major artery of the amazon rainforest, along the stretch of Tumbes - Gualaquiza; which proposes to conduct the continuous monitoring of earth movement in the main amazon highway of the above-mentioned stretch, focusing on the sites potentially affected by landslides over a period of 6 months, This is analyzed once a month in order to relate them with three fundamental factors such as: Rainfall, soil type and the quality of rock mass. The tracking and monitoring was carried out by placing stakes on the most affected areas, in which the terrain displacement was measured with total station and checked with Differential Global positioning System (GPS). Initially, a geological survey was applied on the stretch of ground studied in order to identify lithological, geomorphological and hydrological units, as well as a detailed description of landslides and characterization of rock masses by using Bienansky Rock Mass Rating method, we conducted a sample collection on every site affected. Also, we labelled it and took it to the laboratory for further analytical tests of the soil respectively. Moreover, Rainfall results were gathered through climatic sensors positioned In the Gualaquiza Canton. Once all the information had been collected properly, we continued with the data process and the establishment of the relationship among the three main factors directly linked to the ground movement.
