【摘要】 为预防地铁盾构施工安全事故,利用迭代自组织数据分析算法(ISODATA)对收集到的57起事故和186个未遂事件报告结构化数据进行聚类分析;通过对比分析各聚类集群相对风险可能性的量化结果,探讨地铁盾构施工的安全风险规律及管理对策。结果表明:始发-到达阶段地质条件复杂、洞口土体加固及降水不当是地铁盾构施工领域最危险的风险因素;针对事故风险较大的盾构始发-到达阶段,运用施工安全生产工艺学方法作为安全风险管理对策,可提高地铁盾构施工安全管理绩效。更多还原

【Abstract】 In order to prevent the metro tunnel construction safety accidents,a clustering analysis was made for the cluster was established data on both 57 accidents and 186 near misses using the by ISODATA clustering algorithm. Safety risk rules and management countermeasures were explored for metro shield construction by means of making a comparison between quantification results of the relative risk possibility of the clusters. The results show that the complicated geologic conditions,improper soil reinforcement and drainage at the launching-arrival stage are the most dangerous risk factors in metro shield construction,and that to improve the safety management performance of metro shield construction,the safety production technology of construction should be used at the launching-arrival stage.更多还原
