岩体中含有裂隙、节理、剪切、断层等不同尺度的不连续面,形成离散的裂隙网络。裂隙网络的几何形状和裂隙表面条件控制着岩体的强度和变形行为,而DFN的几何形状和连通性会影响地下水的流动和污染物的迁移。这项研究计划的动机是探索和测试创新的基于规则的地统计学方法在推导明确尊重裂缝网络几何和空间特征的特定地点DFN的改进实现方面的应用。
英文摘要
Rock masses contain discontinuities at different scales, such as cracks, joints, shears and faults, forming discrete fracture networks (DFNs). The geometry of these fracture networks and the fracture surface conditions control the strength and deformation behaviour of rock masses and the geometry and interconnectivity of a DFN can influence groundwater flow and contaminant mobility. The motivation of this research program is to explore and test the application of innovative rule-based geostatistical methods in deriving improved realizations of site-specific DFN's that explicitly honour fracture network geometry and spatial characteristics.
