Análisis de estabilidad del macizo rocoso del talud de la Vía Utuana Tacamoros km 10+970 al km 11+450, parroquia Tacamoros, cantón Sozoranga y propuesta de medidas de mitigación

Abstract

Abstract:The research project is focused on the stability analysis of the section from km 10+950 to km 11+450 of the Via Utuana-Tacamoros, cantons of Calvas and Sozoranga. For this purpose, different methods of topographic survey, geological-structural survey, Refraction Seismic, Electrical Resistivity Tomography and physical-mechanical tests were applied and used. Thus, it was determined that the rocky mass is of medium quality and partially stable, according to the results of the RMR, SMR and GSI classifications. After that, through the analysis of the stereographic nets, it was determined that the slope presents falling blocks which can fail mostly by direct and rotational overturning breakage, and in some blocks by wedge. On the other hand, due to the quality of the massif, it was determined that the results of safety factors are between 1.249 and 1.454, of which when modifying the geometry, high stability indexes are considered, being the same of 1.821 and 1.868. Considering these results, the implementation of elastic reinforcement mesh was determined as a mitigation measure.
