Routine in-situ and laboratory investigations carried out for the basic design failed to provide reliable values for compressibility and consolidation parameters of soft clay layers at the site of a terminal to be built in Santos. A pilot embankment was designed and built divided in three equal areas, two with wick drains in a square mesh at spacings of...
View ArticleIn the design and evaluation of the behavior of embankments on soft clay foundations, geotechnical characterization, along with instrumentation for measurements involving pore pressure and displacements (vertical and horizontal), are required in order to efficiently elaborate a construction. This paper presents the results of stability analysis, and sta...
View ArticleThe 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...
