This paper intends to consolidate the theory of risk management into practical applications in geotechnical engineering, presenting concepts, clarifying procedures and discussing openly its difficulties and trends. It brings the evolution of the risk concept and its application to engineering, worldwide and in Brazil, showing the trend of risk management as a de...

In this paper geotechnical design is addressed and particularly Static and Seismic Pile Foundation Design by Load Tests and Calculation Models. Within this framework Eurocode 7 Geotechnical Design and Eurocode 8 Design of Structures for Earthquake Resistance are introduced. The ultimate limit states and the serviceability limit states are discussed. Potentia...

In embankment dams and dam foundations, internal erosion is the major cause of structural dam failures and incidents. Internal erosion develops locally along concentrated leaks or in the largest flow velocity zones, where the permeability is high, and at the interface between coarse and fine materials, where the flow velocity in coarse material maybe high compar...

Three case histories of dam engineering related topics are presented as previous knowledge and experience would not have led to predict their impact on dam design. The Lecture honours Prof. Victor de Mello by discussing the Balbina HPP where Prof. de Mello led the saprolite foundation design when ancient termite canaliculae were found, imposing the need to contr...
