Pore-scale insights into the mechanisms of tunnel erosion in loess revealed by X-ray micro-CT

This dataset provides the raw and derived data used in the manuscript “Pore-scale insights into the mechanisms of tunnel erosion in loess revealed by X-ray micro-CT”. The data include 3D reconstructed pore structure data, pore morphological parameters, disintegration experimental results, and associated analytical outputs. These materials support the investigation of how pore architecture, pore connectivity, and preferential flow paths influence hydraulic behavior and the initiation of tunnel erosion in loess. The dataset can be used for verification of the reported results and for further research on soil structure, erosion processes, and loess geomorphology.本数据集提供了学术论文《X射线显微CT（X-ray micro-CT）揭示黄土隧道侵蚀机制的孔隙尺度洞察》所使用的原始数据与衍生数据。数据集涵盖三维重构孔隙结构数据、孔隙形态参数、崩解试验结果及相关分析产出成果。这些数据支撑了关于孔隙结构、孔隙连通性（pore connectivity）、优势流路径（preferential flow paths）如何影响黄土水力特性及隧道侵蚀起始过程的研究。本数据集可用于验证已报道的研究结果，亦可用于土壤结构、侵蚀过程及黄土地貌领域的后续研究。
