O comportamento da interface solo/geossintético tem vindo a ser estudada, desde 1995, por umgrupo de investigadores da Faculdade de Engenharia da Universidade do Porto. Para o efeito foram realizadosensaios de arranque, de corte direto e de corte em plano inclinado utilizando diferentes tipos degeossintéticos, nomeadamente geotêxteis, geogrelhas e geomembranas confinados em solos granulares. Seráapresentado um tratamento global dos resultados obtidos com geogrelhas ensaiadas ao arranque, com oobjetivo de obter correlações entre o coeficiente de resistência da interface, f, e as condições de aplicação dediferentes tipos de geogrelhas e solos. O tratamento estatístico das diferentes correlações permitiu obter umaequação geral entre o coeficiente de resistência da interface, f, e a tensão de confinamento, a granulometria ecompacidade do solo e a estrutura das geogrelhas, que é o objetivo principal do presente estudo.
Intensive researches on soil/ geosynthetic interface behaviour have been developed, since 1995, by a research group of the University of Porto (Portugal). In this research soil /geosynthetic interface behaviour was characterized by performing pullout, direct shear and inclined shear tests with different types of geosynthetics, namely, geotextiles, geogrids and geomembranes, confined by granular soils.An overall treatment of the research collected data from geogrids pullout tests will be presented, in order to define significant correlations between the interface coefficient, f, and the application conditions of different types of geogrids and confining materials. By applying statistical analysis to the different correlations it was possible to obtain a general equation for soil compaction conditions, confining stress and interface resistance coefficient, f, which is the corollary of the present research.
