In this paper, the slope rock mass is numerically characterized by considering hydraulic and mechanical properties using two distinct element models. The flow rate and permeability are calculated from localized fluxes through rock masses with varied fracture orientations and scales. Flow models suggest that rock mass permeability is predominantly controlled by fracture size. High rock mass permeability is simulated when the fractures are enlarged. Hydraulic anisotropy is captured when the difference in the fracture size is amplified. The mechanical properties of the slope rock mass are characterized through numerical shearing tests. In general, high permeability corresponds to low shearing resistance of the rock mass. The fractures obliquely distributed to shearing direction lead to additional shearing resistance. Enlarged fractures reflect high conductivity of the rock mass structure and decrease the shearing resistance. Mechanical anisotropy of the rock mass is also captured and attributed to the difference in the fracture size. The relations between hydraulic and mechanical properties are examined, and negative exponential relations are fitted between rock mass cohesion and permeability. The research introduces permeability as reference to slope rock mass characterization and provides reliable methods to this challenging issue.

在本文中，通过使用两个不同的元素模型，通过考虑水力和力学特性，对边坡岩体进行了数值表征。流速和渗透率是通过具有不同裂缝方向和尺度的岩体中的局部通量来计算的。流动模型表明，岩体渗透率主要受裂缝大小控制。当裂缝扩大时，模拟出了较高的岩体渗透率。当裂缝尺寸的差异被放大时，水力各向异性被捕获。斜坡岩体的力学性能通过数值剪切试验来表征。通常，高渗透率对应于岩体的低抗剪强度。沿剪切方向倾斜分布的裂缝会导致额外的剪切阻力。扩大的裂缝反映出岩体结构的高电导率并降低了抗剪强度。岩石质量的机械各向异性也被捕获，并归因于裂缝尺寸的差异。检查了水力和力学性能之间的关系，并在岩体凝聚力和渗透率之间建立了负指数关系。该研究引入渗透率作为斜坡岩体表征的参考，并为解决这一具有挑战性的问题提供了可靠的方法。岩体凝聚力与渗透率之间呈负指数关系。该研究引入渗透率作为斜坡岩体表征的参考，并为解决这一具有挑战性的问题提供了可靠的方法。岩体凝聚力与渗透率之间呈负指数关系。该研究引入渗透率作为斜坡岩体表征的参考，并为解决这一具有挑战性的问题提供了可靠的方法。
