在微观分析中，材料的特征在于三维（3D）微观结构，其由诸如孔隙、空隙和裂纹的组成元素组成。材料的力学和水文特性在很大程度上取决于其微观结构。为了在微观结构水平上讨论地质材料的力学，需要关于其3D微观结构的详细信息。X射线计算机断层扫描是一种强大的非破坏性的方法，用于确定微观结构，但它可能很难确定材料的微观结构从重建的3D图像。我们成功地评估了多孔和纤维材料的三维微结构各向异性使用多方向扫描线的方法，采用简单的图像分析，其结果是可视化的立体网投影。[doi：10.2320/材料trans. I-MRA 2007842]
In microscopic analysis, materials are characterized by a three-dimensional (3D) microstructure which is composed of constituent elements such as pores, voids and cracks. A material’s mechanical and hydrological properties are strongly dependent on its microstructure. In order to discuss the mechanics of geomaterials on a microstructural level, detailed information on their 3D microstructure is required. X-ray computed tomography is a powerful non-destructive method for determining the microstructure, however it can be difficult to determine a material’s microstructure from the reconstructed 3D image. We successfully evaluated the 3D microstructural anisotropy of porous and fibrous materials using a multi-directional scanning line method that employs straightforward image analysis, and its results were visualized using stereonet projection.
