Analysis of the oedometer stress path
Résumé
A new oedometer ring is used to study the relationship between applied vertical stress and the measured lateral stress during the oedometer test. This paper presents the new equipment and some results, from tests on Saint-Herblain clay (France), to demonstrate its performance. The measurement in continuous of the lateral stress allows thus to precise, in a (q, p') diagram, the oedometer stress path.
