Assessment of Rate Effects in Piezocone Tests from Poroelastic Cavity Expansion Analysis

September 18, 2018
Cavity expansion solutions are often used in geomechanics modelling to investigate problems such as the bearing capacity of piles or interpretation of cone and pressuremeter tests. Conceived as a simplified approach to capturing the transient flow effects in the soil around an expanding cylinder, a non-linear poroelastic model is formulated in this paper based o...

Assessment of the Stress History of Quaternary Clay from Piezocone Tests

May 16, 2018
This paper highlights the importance of linking regional geology to geotechnical ground investigation when estimating the pre-consolidation pressure σ’p of Quaternary clay deposits from piezocone tests. The work comprises a comprehensive site characterization from boring logs, piezocone tests and laboratory oedometer tests carried out at the Tubar&atild...

Stabilised Soil Layers Enhancing Performance of Transverse-Loaded Flexible Piles on Lightly Bonded Residual Soils

September 21, 2017

A set of crosswise-loaded flexible piles was tested in binder stabilised top sand layers embedded in lightly bonded residual soil. Slope indicators were used to measure horizontal displacements in free-headed flexible piles during all loading stages. The geometry of the cement stabilised top sand layer surrounding the piles varied from about 2 to 4 time...

Remediation Techniques Applied in Residual Clayey Soil (Oxisol) Contaminated by Diesel and Biodiesel

August 02, 2013

Biodegradation in residual basaltic soil contaminated by diesel fuel and biodiesel was assessed by three different techniques comprising natural attenuation, bioaugmentation, and bioventing. The soil was described in terms of its
physicochemical and microbiological characteristics, showing favorable bioremediation conditions. Natural attenua...
