A Georeferenced Dataset of Historical Subgrade Defects in China’s High-Speed Railways

We developed a comprehensive georeferenced dataset that encompasses defect records extracted from peer-reviewed literature published between 1999 and 2023 in China. The dataset consists of georeferenced records for eight different defects, spanning across 661 locations and categorized at various scales, ranging from provinces to townships. The most commonly reported defect types include subgrade settlement, frost damage, uplift deformation, and mud pumping. This dataset provides an comprehensive map of historical subgrade defects affecting high-speed railways in China. It could facilitate operational risk assessments and the prediction of subgrade performance.这是一个全面的地理参考数据集，包含从 1999 年至 2023 年间在中国发表的同行评审文献中提取的缺陷记录。我们的调查包括中英文期刊文章、会议论文和学位论文。实施了严格的质量控制程序，以消除重复数据并确保数据集的准确性。生成的数据集包含 8 个不同缺陷的地理配准记录，跨越 661 个位置，并以不同的比例进行分类，从省到乡。这个新数据集提供了影响中国高速铁路的路基缺陷的最新地图。它可以作为一种宝贵的资源，促进随后的运营风险评估和路基性能的预测。<br>
