Aplicação de métodos de agrupamento para definição de famílias de descontinuidades

Abstract

This work had the purpose of applying numerical and classical methods of clustering for the definition of discontinuity sets in order to use the results in rock slope stability studies. In general classical methods are employed, involving the use of pole density diagrams to define these sets. However there can be uncertainties in family sets interpretation, especially when discontinuity family frequency is very distinct. In these cases the use of numerical methods to define family sets, associated to classical methods in order to interpret, validate and represent the sets is interesting, as they complement each other. Data used in this work was obtained from geotechnical surveys along a mine, an urban slope and a road slope, where discontinuity orientations were measured. Softwares developed in FORTRAN language were used in the definition of discontinuity sets. Average values of orientation and dispersion parameters of discontinuity sets were calculated, as the distribution probability data function was obtained. Field observations demonstrated the reliability of the clustering method used.
