文章以邢衡高速大型交叉工程为依托,结合邢衡高速大型交叉施工安全事故的特点,以钻孔灌注桩为例,考虑其工程隐蔽性,利用事故因果连锁理论之海因里希事故因果连锁理论,分析了邢衡高速大型交叉施工安全可能发生事故的原因,并提炼出适应于邢衡高速大型交叉施工安全的防治措施。 The article relies on the Xing-Heng high-speed large-scale cross-engineering, combined with the characteristics of Xing-Heng high-speed large-scale cross-construction safety accidents. Taking the bored pile as an example, considering its engineering concealment and using the causal chain theory of accident causal chain of Heinrich accidents Theory, analyzes the possible causes of accidents in the safety of large-scale cross-construction of Xing-Heng Expressway, and sums up the control measures for the safety of large-scale cross-construction in Xing-Heng Expressway.
