Abstract
White-light speckle photography was applied to measure the viscoplastic deformation of a proposed nuclear-waste repository. The repository vaults are carved into bedded salt deep in the earth, and deform extremely slowly. The research demonstrates the feasibility of using whole-field techniques to detect mine wall strains, confirms certain, but not all, measurements of point-by-point instruments, and also confirms the predictions of a site-specific numerical model.
