摘要: 为准确预测地铁车站施工高处坠落可能性,构建基于HFACS-BN的地铁车站施工高处坠落可能性评价模型。首先,基于人为因素分析和分类系统(HFACS)框架,识别地铁车站施工高处坠落致因因素,并将其映射为贝叶斯网络(BN);然后,将基于正态分布权重的群决策法、模糊最佳最差法(fuzzy-BWM)、全局相对值等方法相结合,并应用到BN中获取根节点的先验概率和中间节点的条件概率,依托BN的正向推理计算高处坠落节点处于各状态下的概率,敏感性分析辨识关键致因因素;最后,选取成都地铁11号线3个车站进行实例分析。研究结果表明:回龙路站、钓鱼嘴站和芦角村站的高处坠落最可能状态分别为严重故障、无故障、无故障状态,均与实际施工情况基本一致;安全教育培训不到位、移除防坠落x措施、踩空踩滑、安全意识薄弱、站在不安全位置、照明不足为高处坠落事故的关键致因因素,应重点管控。

Abstract: In order to accurately predict falling possibility at height in subway station construction, an evaluation model of it based on HFCAS-BN was constructed. Firstly, based on HFACS framework, causes of falling at height were identified, and the framework was mapped into BN. Secondly, group decision-making method based on normal distribution weight, fuzzy-BWM and global relative value were incorporated into BN to obtain prior probability of root nodes and conditional probability of intermediate nodes. Then, probability of falling nodes in various states was predicted and key causes were identified by using BN forward reasoning and sensitivity analysis. Finally, three stations of Chengdu Subway Line 11 were selected for case analysis. The results show that evaluations of most possible state of Huilonglu Stop, Diaoyuzui Stop and Lujiaocun Stop, respectively severe fault, fault free and fault free, are basically consistent with actual construction situation. Key causes of falling accidents include inadequate safety education and training, removal of falling prevention measures, losing one's footing, poor safety awareness, standing on unsafe places and inadequate lighting, so major efforts should be made on them.
