城市轨道交通工程建设期间危险有害因素分析

Analysis on Hazardous and Harmful Factors in Construction Process of Urban Rail Transit Engineering

通过对国内城市轨道交通工程建设期间典型事故的统计分析,总结城市轨道交通工程建设期间可能存在的危险有害因素。分析结果表明,城市轨道交通工程建设期间事故多发的主要原因有:不同施工工法引起的地层坍塌和结构物破坏;不良地质体诱发的安全事故;地下管线引起的安全事故;沿线临近建筑、构筑物引起的安全事故;施工管理不当造成的安全事故等。

By statistical analysis on the typical accidents during the construction process of urban rail transit engineering in China,the hazardous and harmful factors existing in the construction process were summarized. The results show that main causes for frequent accidents in the construction process of urban rail transit engineering include：the formation collapse and structure destruction caused by different construction method,safety accidents induced by unfavorable geological body,safety accidents by underground pipelines,safety accidents by adjacent buildings and structures along the rail,safety accidents by improper construction management,etc.
