Phenomena that do not obey Terzaghi’s principle of effective stress (PES) are related to strain rate and time effects. This issue led the author to refer to early articles in soil mechanics, which used to consider the shear resistance of clays as a combination of two components: a frictional and a viscous one. In these articles the viscous com...

Advances in equipment and tools implemented for geotechnics have been allowing design to be supported by numerical simulations. However, even with sophisticated resources, the dam geotechnical engineering industry still lacks few information on laboratory parameters as in the case of Concrete Face Rockfill Dams (CFRD). It is necessary to simplify the us...

Geosynthetic geofoam has a cellular structure made of expanded polystyrene (EPS) and has been used as a lightweight material for geotechnical use in embankments, bridges seat, base and sub-base of roads pavements and infrastructure protection applications. This paper presents research data on EPS laboratory tests aiming to characterize Brazilian EPS for...

This paper reviews the behaviour of reinforced embankments on soft ground. Case of the Almere test embankment is used as an example to demonstrate the key function of reinforcement in improving the performance of embankments on soft
foundation. The effects of partial drainage are summarized for reinforced embankments and contrasted the resul...
