“…Claystones are sensitive to changes in hydric conditions that can lead to the shrinkage or the swelling of the clay matrix (Galle, 2001;Kang et al, 2003;Soe et al, 2007;GascBarbier and Tessier, 2007;Cosenza et al, 2007;Pineda et al, 2010;Hedan et al, 2012;Renard, 2012;Wang et al, 2013Wang et al, , 2015Desbois et al, 2014).…”

Abstract. The macroscopic description of deformation and fluid flow in mudrocks can be improved by a better understanding of microphysical deformation mechanisms. Here we use a combination of scanning electron microscopy (SEM) and broad ion beam (BIB) polishing to study the evolution of microstructure in samples of triaxially deformed Callovo-Oxfordian Clay. Digital image correlation (DIC) was used to measure strain field in the samples and as a guide to select regions of interest in the sample for BIB-SEM analysis. Microstructures show evidence for dominantly cataclastic and minor crystal plastic mechanisms (intergranular, transgranular, intragranular cracking, grain rotation, clay particle bending) down to the nanometre scale. At low strain, the dilatant fabric contains individually recognisable open fractures, while at high strain the reworked clay gouge also contains broken non-clay grains and smaller pores than the undeformed material, resealing the initial fracture porosity.

“…This approach is simple to use and can be applied in many experiments on materials and for various scales. In the geosciences, the ability of the DIC method to observe strain localization in geomaterials (e.g., Bésuelle et al, 2000) and to detect cracks in clay rocks (e.g., Hédan et al, 2012Hédan et al, , 2014 has been demonstrated. Moreover, this optical method coupled with environmental scanning electron microscopy (ESEM) has recently been applied to clay-rocks and clay films (Carrier et al, 2013).…”

“…e DICM was also used to test rock-like material cylinders [15][16][17][18] and blocks [19][20][21][22][23][24][25][26][27][28] in small scales. Dautriat et al [15,16] observed the deformation field evolution of limestone cylinders under different scales in compression experiment by the DICM.…”

“…Cheng et al [17] carried out the uniaxial compression tests on a series of composite rock specimens with different dip angles, whose diameter was 150 mm and height was 500 mm, and found that the specimens had obvious plastic deformation during loading and the brittleness of the specimens gradually increased during the loading process. Hedan et al [18] analyzed deformation mechanisms induced by desiccation in Tournemire argillite specimens with a height of 200 mm and a diameter of 78 mm using the DICM.…”

e digital image correlation method (DICM) has been applied to similar material simulation experiments for rock-like materials, to overcome the weakness of traditional measurements, for example, data discontinuous. In this paper, the movement and fracturing process of the overlying strata during excavation are observed and studied, and the distributions of stress, strain, and deformation in the overlying strata are obtained based on similar material simulation. e DICM is applied to improve the testing method and to optimize the discontinuity of testing points; of course, the difference of rock deformation in the overlying strata during excavation is considered. Full-field deformation and strain are analyzed by the DICM. To verify the accuracy of the DICM, results obtained from the DICM, numerical simulation and similar material simulation, are compared. e DICM can reflect the characteristics of locality and randomness of rock-like materials more real than numerical simulation, and comparing with similar material simulation, it can directly reproduce the movement and fracturing process of the overlying strata during full-field excavation. It shows that, the DICM is entirely feasible to using in the large scale full-field deformation measurement on complex rock structure, and it is of theoretical importance for testing for rock-like materials.
