Shear Behavior and Anisotropy Characteristics of the Fracture Morphology of Sandstone with Different Water Contents by Changang Du, Lulu Sun, Botao Qin, Jiang Xu, Yixin Liu

“…To investigate the weakening effect of water content on the mechanical properties of a rock mass, laboratory direct shear tests combined with three-dimensional analysis of sheared surfaces were carried out on sandstone samples with different water contents. The variogram parameters, sill and range, were applied to quantify the morphology of shear fracture surfaces, to reflect the shear failure process of the intact rock, and to provide a basis for resliding instability of jointed rock. …”
