泥石流拦挡坝（DFBD）不仅会改变原有的水文和地质条件，还可能引发次生灾害，如溃决洪水和上游侵蚀。有关 DFBD 的数据对相关研究至关重要。然而，目前尚未建立 DFBD 数据集。为了填补这一空白，我们采用了严格的数据收集和验证流程，查阅了 2519 篇文献和媒体报道，构建了一个包含 555 个 DFBD 事件的数据集。该数据集全面记录了泥石流灾害的 36 项属性，包括地点、国家、触发因素、形成日期、可靠性、泥石流密度、泥石流速度、坝长、坝高、坝宽、坝容积、阻挡方式、稳定性、寿命、坝体材料、湖长、湖容积、湖面面积、溃坝机制、峰值排水量和生命损失等。

Data on DFBDs is crucial for related research. However, there is no dataset for DFBDs has been established. To fill this gap, we adopted a rigorous data collection and validation process, reviewed 2519 literatures and media reports, and constructed a dataset of 555 DFBD events. The dataset comprehensively records 36 attributes of the DFBDs, including location, country, trigger, the date of formation, reliability, debris flow density, debris flow velocity, dam length, height, width, volume, blocking mode, stability, longevity, dam material, lake length, lake volume, lake area, failure mechanism, peak discharge, and loss of life, etc.
