Determinationofelasticmodulus of claystone:Nano-/micro-indentation andmeso-compression tests used to investigate impact of alkaline fluid propagation over 18 years
《Journal of Rock Mechanics and Geotechnical Engineering》2017年第3期129-136,共8页Danièle Bartier Christophe Auvray 
GNR NEEDS-MIPOR for funding this project
Micro-mechanical properties of a claystone were tested after undergoing alkaline perturbation on site(Tournemire,CD borehole)for 18 years.In a saturated context and outside the excavation disturbed zone(EDZ),the clays...
