摘要
城市地下综合管廊施工常会途经环境敏感区。利用事故树对环境敏感区施工风险进行分析,建立顶上事件及造成事故发生原因之间的逻辑关系树,进行定性及定量分析环境敏感区施工存在的潜在风险。对事故树最小径集计算结果可知,施工资质和施工顺序这两个基本事件结构重要度最大,表明施工资质不符和施工顺序有误对于事故发生占首要地位,因此应将这两项基本因素作为预防事故发生着重考虑的因素。
The construction of urban underground comprehensive pipe gallery often passes through environmentally sensitive areas.The accident tree is used to analyze the construction risks in environmentally sensitive areas,and a logical relationship tree between the overhead events and the causes of the accidents is established to qualitatively and quantitatively analyze the potential risks of construction in environmentally sensitive areas.From the calculation results of the minimum diameter set of the accident tree,it can be seen that the two basic events,construction qualification and construction sequence,have the greatest structural importance,which indicates that the construction qualification is not up to standard and the construction sequence is wrong are the two factors to be considered in preventing accidents.
