This paper discusses the field monitoring of an experimental embankment divided into two symmetrical instrumented sections constructed with two clays treated with lime and/or cement in the northeast of France. The soil-atmosphere interaction is investigated in the monitored embankment. The field instrumentation included spatial and temporal changes of t...
View ArticleWhen soils are inundated with liquids other than water, a physicochemical interaction takes place and can alter the soil behavior. Depending on the type of soil and on the solution, the soil can become more compressible and lose strength (or the contrary). In this paper, tropical residual gneiss soils are used, namely lateritic and saprolitic soils. The...
View ArticleIn the Metropolitan Region of Recife, Northeast Brazil, landslides caused a total of 214 deaths between 1984 and 2012. Efforts have been made, but there is still need to improve the risk area management by discovering the correlations between the rainfall and landslides and by implementing a disaster warning and prevention system in order to reduce the ...
View ArticleThis study analyses the real applicability of laser scanning techniques to determine bulk densities of fine grained soils. The method, fast and accurate, can be employed both in the field and laboratory. The technique was calibrated with benchmarks and then applied to measure volumes of small samples of a specific silty soil of well-known properties (gr...
