TL;DR: The use of high-resolution tomographic techniques has allowed for unprecedented observations and a renewed understanding of geomaterials and processes, such as subsurface volume loss in sandy soils can cause the formation of sharply defined low-density pipes, cryogenic suction consolidates sediments next to ice lenses during ground freezing, root growth involves transverse expansion, and the stress relaxation at the tip facilitates further longitudinal invasion; blade insertion causes successive shear localizations as discussed by the authors.

TL;DR: In this article, the authors describe the stability of a breakwater foundation under the action of seepage based on the results of model tests and FEM analyses and reveal the effect of the reduction in bearing capacity.

TL;DR: In this paper, the deformation and failure of a soil under triaxial compression using in situ X-ray computed tomography (CT) and digital image correlation (DIC) was investigated.

TL;DR: In this article, a tsunami overflow-seepage-coupled centrifuge experimental system was developed and applied to investigate the concurrent processes, and to elucidate the mechanism, of the instability involving the scour of the mound/sandy seabed, bearing capacity failure and flow of the foundation, and the failure of caisson breakwaters, with high-resolution image analysis.
