城市轨道交通施工风险统计及事故特征分析

Urban rail transit construction risk analysis and accident characteristics statistics

为分析城市轨道交通施工风险统计事故特征,本文从明挖法、盖挖法、暗挖法、盾构法、矿山法、高支模等施工方法入手,对施工危险因素进行辨识分析,提出在设计、施工阶段应重点关注的风险点。基于国内某地铁施工期间发生的事故事件数据,统计分析其事故类型并提出事故类型规律性特征,研究结果可为类似施工工程提供参考依据。

In order to analyze the construction risk and accident statistics of urban rail transit,this paper identifies and analyzes the construction risk factors from the construction methods of open-cut method,cover excavation method,underground excavation method,shield method,mine method and high formwork are identified and analyzed in this paper,the risk points that should be paid attention to in the design and construction stages are also put forward.Based on the accident data of subway construction in China,the statistical analysis of the accident types is carried out,and the regularity characteristics of the accident types are put forward,which provides reference for similar construction projects.
