Estudo de previsão de escorregamento a partir do fator de segurança 3D: Campos do Jordão-SP

Abstract

This work presents a review of procedures for landslides studies, with focus on the methodologies of forecasting from the combination of knowledge of hydrological modeling and analysis based on deterministic evaluation of the 3D factor of safety. It was developed a set of procedures for the prediction of landslides on scales larger than 1:10,000, and these were applied in eight areas in the city of Campos do Jordão (SP). The results for these areas are very promising and reflected the geological, geotechnical and hydrogeological conditions in each area.

Evaluation of the Bioactivity Behavior of a 48 Wt %SiO₂ Bioglass through Experiments in Simulated Body Fluid

“…4 shows the DRIFT spectra of the bioglasses samples after diferente periods in SBF immersion. The results indicate that for longer periods it is observed the formation of peaks near 515-530 and 600-610cm-1, corresponding to the crystalline P-O bonding [8]. Moreover, the peaks near to 550-560cm-1, related to vitreous P-O bonding [8], were with lower intensity.…”

These observations suggest that the phosphorous of the glass network is percolated to the surface as SBF solution effect.…”

Estudo Dos Fatores De Segurança Em Análises Por Equilíbrio Limite Em Modelos Bi E Tridimensionais

“…No presente trabalho será aplicado, especificamente, o método determinístico para o cálculo da estabilidade de taludes. Estas análises são baseadas nas leis físicas de conservação de massa, energia e momentum (quantidade de movimento), e objetivam estimar um valor de fator de segurança a partir dos dados geométricos e parâmetros de resistência e de percolação do maciço (Silva, 2009).…”
