天津地铁4号线南段工程（河北大街站（不含）～东南角站（不含））地质钻孔数据集

该数据集包括地铁集团轨道交通线路地质钻孔相关数据，对采集的钻孔数据电子化，进行清洗、关联与标签化处理，去除无关字段、对敏感信息进行脱敏，在此基础上利用模型对数据质量进行分析检查，通过预定义的完整性规则集对地址钻孔数据进行校验检查，识别是否存在数据缺失、不完整或违反完整性约束的情况，比如识别是否完全重复或关键字段重复、对数据字段进行完整性检查（空值检查、默认值检查等）等，保证数据集的完整性和可用性，汇集形成地铁4号线南段工程（河北大街站（不含）～东南角站（不含））地质钻孔数据数据集。

This dataset encompasses relevant geological borehole data for rail transit lines of the subway group. The collected borehole data is first digitized, followed by data cleaning, correlation processing and labeling. Irrelevant fields are removed, and sensitive information is desensitized during this stage. Subsequently, models are utilized to analyze and inspect the data quality. Predefined integrity rule sets are applied to validate the geological borehole data, identifying issues including data missing, incompleteness, or violations of integrity constraints. Specifically, the detection covers full duplicate records or duplicate key fields, as well as integrity checks on data fields such as null value verification and default value inspection. These steps ensure the integrity and availability of the dataset, and finally a dedicated dataset of geological borehole data for the southern section of Metro Line 4 project (from Hebei Avenue Station (excluded) to Southeast Corner Station (excluded)) is compiled.
