Fuzzy

The purpose of this article is to present predictive models of dilation and shear stress of rock discontinuities by applying the neuro-fuzzy technique, which uses a) the high capacity of artificial neural networks (ANN) to understand and to model complex multivariate phenomena, and b) the concepts of fuzzy sets theory to consider the variability of the ...

As a result of a number of studies, some analytical models have been developed to predict the shear behavior of unfilled rock joints, but they all present a purely deterministic nature because their input variables are defined without considering the uncertainties inherent in the formation processes of the rock masses and related discontinuities. This work aims ...

This paper shows the use of fuzzy logic to evaluate the effectiveness of the reinforcement of Santa Branca dam. The embankment reinforcement was found imperative once the dam had shown signs of instability process, as undesirable seepage and unexpected movements, just after the first impoundment. Stability analyses were carried out considering fuzzy var...
