Compressibility and consolidation properties of Santos soft clay near Barnabé Island

November 10, 2021

A geotechnical study based on characterization tests and seventy incremental loading onedimensional consolidation tests was carried out on high-quality undisturbed samples taken from Santos Harbor Channel subsoil near to Barnabé Island, where a pilot embankment was built. The characterization profiles revealed a stratigraphy following the pat...

A Laboratory Study of the Collapse Behaviour of a Compacted Sabkha Soil

March 24, 2020
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...
