数据集来源于库坝系统案例收集，包括课题现场调研收集材料整理，另外包括对公开文献数据收集整理，还有一部分包括工程实践中数据收集。
", "ds_process_way": "(1) 数据采集与甄选：通过系统收集库坝系统的历史工程案例、现场调研记录及相关公开文献，重点筛选洪水、地震、地质灾害等极端条件下的灾损记录，确保数据涵盖挡水、泄水建筑物及金属结构设施等多种场景。
\n(2) 信息提取与分类：从原始资料中提取关键实体信息，将缺陷类型（如深水裂缝、渗漏、淤积、止水破损、结构性破损、洪水漫顶、岸坡滑坡等）与受损部位进行标准化分类和编码。
\n(3) 关系型数据构建：建立“缺陷-修复-材料”的多维映射关系，将提取的缺陷案例与对应的修复工艺技术、修复材料进行匹配关联，形成结构化的关系型数据表，以支撑不同缺陷场景下的修复方案检索。
\n(4) 数据清洗与校验：组织专业技术人员对录入的工艺参数、材料性能指标及修复案例细节进行核对与去重处理，修正数据不一致性，最终形成规范化的关系型数据集。
