<p>The use of granular column is one of the ground improvement methods used for soft soils. This method improves the foundation soils mechanical properties by displacing the soft soil with the compacted granular columns. The columns have high permeability that can accelerate the excess pore water pressure produced in soft soils and increase the undrained s...

<p>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 hi...

Considering the increasing incidence of cyclic loadings on engineering structures and the enhancement of design analysis, soil testing under cyclic conditions has renewed its importance. Laboratory tests are conducted to simulate as near as possible field conditions. Assumed conditions aid on the choice of the tests to be conducted in order to determinate the re...

<p>Compacted earth embankments are routinely used in dams and many others infrastructure projects in Brazil. It is common to use fine-grained soils for these embankments, which are placed and compacted in the field at specific values of unit weight and water content. Their design is usually performed using geotechnical parameters from laboratory tests on c...
