基于组合赋权关联规则的塔吊事故成因分析

为有效提高我国塔吊安全水平，揭示塔吊事故内在联系，利用改进Apriori算法，挖掘塔吊事故关联规则。首先，收集210份塔吊事故调查报告，根据事故调查报告、文献分析提炼塔吊事故基本属性和致因属性。然后，基于不同的事故阶段，提出组合赋权和定向约束的改进关联规则算法，并对塔吊作业事故影响因素进行定量分析，挖掘潜在映射关系。最后，根据挖掘结果，分析塔吊事故关键关联规则，为塔吊事故安全水平的提升提供理论指导，并提出相关建议。

Cause Analysis of Tower Crane Accident Based on Combination Weighting Association Rules

In order to effectively improve the safety level of tower crane in China and reveal the internal relationship of tower crane accidents, the improved Apriori algorithm was used to mine the association rules of tower crane accidents. Firstly, 210 accident investigation reports of tower crane were collected. According to the accident investigation report and literature analysis, the basic attributes and cause attributes of tower crane accidents were extracted. Then, based on different accident stages, an improved association rule algorithm based on combination weighting and directional constraints was proposed, and the influencing factors of tower crane operation accidents were quantitatively analyzed to mine the potential mapping relationship. Finally, according to the mining results, the key association rules of tower crane accidents were analyzed to provide theoretical guidance for the improvement of the safety level of tower crane accidents, and relevant suggestions are put forward.
