The accurate performance of instrumentation is fundamental to the adequate use of the results obtained from
analyzing the behavior of constructions of embankments on soft soils. When evaluating embankment behavior, the
geotechnical instrumentation for pore pressure and vertical and horizontal displacements measurements can be an&...
The use of prefabricated vertical drains with vacuum preloading and surcharge preloading is now common practice and is proving to be one of the most effective ground improvement techniques known. The factors affecting its performance, such as the smear zone, the drain influence zone, and drain unsaturation, are discussed in this paper. In order to evalu...
View ArticleThis article compares and analyses the behaviour of three test embankments. The soil foundation consisted of
normally consolidated clay overlain by a thick sand surface layer. The embankments were rapidly constructed until failure,
which occurred after approximately 50 days. Two of the embankments were reinforced, one including p...
This paper presents and discusses a limited set of results from an extensive testing program which has been
carried out since 1995 at the University of Brasília Experimental Research site. This site is underlain by the typical tropical,
unsaturated and collapsible soil deposit of the Federal District, which has been th...
