大跨扁平浅埋隧道安全风险评估研究

摘要

Taking Longtoushan tunnel as an example,the paper carries out sectioning analysis and comprehensive evaluation of major risk events, puts forward countermeasures of reducing risks,and finally points out that:after adopting rational risk controlling measures,it can greatly reduce tunnel engineering construction risk,furthermore,the integral tunnel risk level is controlled within acceptable scope.%以龙头山隧道为例，对该隧道主要风险事件进行了分段分析与综合评价，并提出了降低风险的对策，指出在采取合理的风险控制措施后，可以大大降低隧道工程建设风险，将隧道总体风险水平控制在可接受范围。
