“…Rock joints, which are ubiquitous in slope, fracture zone, and underground engineering excavation area, have a significantly weaker bearing capacity than the two wall surface rock masses (Yong et al, 2018;Lin et al, 2019a;Wang et al, 2020;Xie et al, 2020a;Zhang et al, 2020a,b). And typically, shear slip failure along joints has dominated the main failure modes of the aforementioned rock engineering under the action of external forces or drastic changes in the geological environment (Meng et al, 2017;Han et al, 2020;Li et al, 2020;Lin et al, 2020a;Yuan et al, 2020). Besides, as the main movement channel of groundwater, the seepage properties of joints also present a powerful influence on the shear mechanical properties of joints.…”
