Stress release and suction generation in the Callovo-Oxfordian claystone
E3S Web of Conferences, 2016 Stress release effects in a specimen of claystone extracted at great depth (465 m) in the layer of the Callovo-Oxfordian claystone in Eastern France is examined by mimicking the stress change during extraction in the oedometer. To do so, a specimen first
