| 摘 要： | 铁路隧道工程具有隐蔽性、不确定性和高造价等突出特点,且在其运营期影响安全的因素较为复杂,因此建立一套有效的风险评价系统是实现运营风险监控预警的关键。通过对铁路隧道运营期的风险因素进行分析,提出隧道运营风险的评价指标体系,运用物元可拓性理论建立铁路隧道运营风险的可拓评判模型,并基于此模型进行了实证分析。

| Abstract: | Railway tunnel has prominent features,such as concealment,uncertainties and high cost and so on,and has more complex factors that affect safety in the period of its operation,therefore,the establishment of an effective risk assessment system is the key to achieve early warning monitoring of operational risk.Through analyzing risk factors of railway tunnel in the period of operation,the assessment index system of operation risk of railway tunnel is put forward,and its extensional evaluation model is establis... |
