CHARACTERIZATION OF THE GEOTECHNICAL UNITS OF THE EASTERN PORTION OF THE METROPOLITAN REGION OF BELO HORIZONTE - MG
This paper presents the characterization of the geotechnical units of the eastern portion of the Metropolitan Region of Belo Horizonte (RMBH). This region is characterized by being a vector of intense development and dense urban mesh, in addition to the occurrence of innumerable mining activities. The geology of the area consists of granite-gneiss rocks of the Belo Horizonte and Caeté Metamorphic Complexes, sectioned by NW/SE and SW/NE fractures systems, and metasedimentary and volcanic rocks of the Rio das Velhas, São Francisco and Espinhaço Supergroups, with foliations and diving, predominantly, to E. The characterization of the described lithologies had as main bibliographic basis the report of the PDDI/RMBH (Master Plan of Integrated Development of the Metropolitan Region of Belo Horizonte), which groups 10 geotechnical units for the entire Metropolitan Region of Belo Horizonte. In this work the geotechnical classification of these units was made from the description of 114 rock masses located on natural and cut slopes. In addition, it was also evaluated the susceptibility to occurrences of geodynamic processes. The results contributed to the creation of a framework of available information on the characteristics of geotechnical units in the RMBH area.
Keywords: geodynamic processes, geotechnical behavior, susceptibility
