overconsolidation ratio
This paper highlights the importance of linking regional geology to geotechnical ground investigation when estimating the pre-consolidation pressure σíp 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...

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 software (GDSlab) which applies ramps of radial stress ...
