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...

Stress History of Soils from Cone Penetration Tests (Manuel Rocha Lecture)

September 01, 2017

Stress history is an important measurement in soils as it affects strength, stability, stiffness, and flow characteristics. The evaluation of the in-situ preconsolidation stress, or effective yield stress, from the results of piezocone penetration tests allows for an economical and expedient means to profile the stress history of clays, sands, and mixed...

K0 Measurement in a Sand Using Back Volume Change

August 26, 2014

An experimental technique, using a computer controlled triaxial test to evaluate the coefficient of earth pressure at rest, K0, is presented. The method does not require the use of any radial measurement transducers and is free from any side friction effects, typical of oedometer testing. It uses commercial so...
