RESUMO
This thesis studies prediction, occurrence and monitoring of movements in rock and soil masses in underground excavations, it is emphasized that the study bases fundamentally on monitoring. A technical methodology is proposed for analysis and interpretation of time series from geotechnical instrumentation measurements, based on geomechanical criteria and classic statistics. The most important variables that define the mechanism are analyzed: movements in underground excavations in rock and soil masses. The results of the analysis are correlations between variables and functional models of variables that characterize rock or soil mass movement in underground excavations construction. The proposed methodology is validated with data from three tunnels with different characteristics. The results of this study are applied to underground mining and to other areas of the extractive industry, since these results came from construction of large urbane tunnels.
