Requiem for risk classification matrices

August 03, 2020
Classification matrices are scrutinized for inconsistencies, errors and deficiencies in meaning. Proper definition, measurement and ranking of risks are demonstrated as compelling arguments whenever risk and reliability analyses of geotechnical structures, such as dams, are required....

A Model of Energy Dissipation for the Mode of Rupture of Shallow Foundations in Sandy Soils

October 01, 2019
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...

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...

Relationship Between Shear Wave Velocity and Piezocone Penetration Tests on the Brazilian Continental Margin

May 12, 2020

A detailed characterization of the shear wave velocity profile is an essential tool in the resolution of a variety of seismological and geotechnical engineering problems. The main objective of this study is to present equations capable of providing reliable shear wave velocity profile estimations based on CPTu parameters. The results of a series of pion...
