Stress-Deformation and Strength Characteristics of a Compacted Shale.

摘要

This thesis reports the results of a laboratory investigation to determine the influence of compaction on the stress-deformation and strength characteristics of a mechanically hard but non-durable shale from the New Providence formation. Kneading compacted specimens were saturated under a low effective confining pressure,consolidated to the desired effective stress,and sheared undrained at a constant rate of strain. The volume changes during isotropic saturation and consolidation,and the axial load and the pore pressure changes during axial compression were observed.
