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...
View ArticleSettlement evaluation in sanitary landfills is a complex process, due to the waste heterogeneity, time-varying properties and influencing factors and mechanisms, such as mechanical compression due to the load application and creep, and physical-chemical and biological processes caused by the wastes decomposition. Many empirical models of analysis and lo...
View ArticleThe use of soil-bentonite mixtures for sanitary landfill liners with the purpose of retaining pollutants is becoming very common. This work shows the results of hydraulic conductivity and shear strength tests performed with soil-bentonite mixtures with bentonite contents of 3%, 5% and 7%. Additionally, shear strength test results carried out with a mixt...
View ArticleThe assessment of problems of imperfect, damaged, pile groups is scarce in the geotechnical literature. Besides, techniques of assessing the performance of the foundation system once a defect is found are seldom presented, as well as real examples of the behavior of large scale imperfect foundations after their remediation. Therefore, this paper has ext...
