Rock Fracture Geometry Data in Form of Grid Coordinate Points

The dataset provides rock fracture geometry data of 30 fracture samples, including granite, marble, and sandstone fractures. Among them, 25 fracture samples (5 rock fractures with different roughness × 5 aperture levels) are used for DNS in the study, and another 5 fracture samples with varying roughness for laboratory experiments.本数据集提供了30组岩石裂隙几何数据，样本涵盖花岗岩、大理岩及砂岩裂隙。其中25组裂隙样本（5种不同粗糙度的岩石裂隙各对应5种开度层级）被用于本研究中的直接数值模拟（Direct Numerical Simulation，DNS），剩余5组粗糙度各异的裂隙样本则用于实验室实验。
