The plastic deformation of sandy soils is poorly understood from a microscopic point of view. The criteria to predict the mode of rupture of shallow foundations are mostly based on phenomenological arguments and may fail to explain the results obtained experimentally in model foundations. This work validates a model to determine the mode of rupture of sandy soil...

This paper aims to explore the potential use of artificial neural networks (ANNs) to predict the compression index (CC) of soft soils from the Brazilian coast. Results from 225 standard consolidation (oedometer) tests and the corresponding soil index properties (i.e., initial void ratio, natural water content and Atterberg limits) of a wide variety of fine-grain...

Brazil has one of the largest hydroelectric parks in the world and important ventures for the world ranking have been executed in the country - to cite the most recent, Jirau and Belo Monte Hydraulic Power Plants (HPP). This emphasizes the importance in the continuous study of techniques and theories commonly used, in order to improve the quality of the projects...

Sabkha soils are saline sediments, which can withstand high loads in dry conditions, but upon wetting, they exhibit significant deformation and low shear strength and hence pose great challenge to engineers. This paper investigates the collapsibility of a compacted sabkha soil of Chott El-Hodna (Algeria) using a modified oedometer, which allows water to percolat...
