| 摘 要： | 在分析、总结风险评估理论的基础上,结合模糊数学多级综合评判理论,建立了隧道洞口仰坡施工期间破坏失稳的概率模型。同时将计算结果引入到风险评估理论中,把失稳概率和风险计算过程结合起来,并尝试建立评价隧道施工期间洞口仰坡的风险评估模型,在此基础上又提出了仰坡风险管理的几种手段,期望能够对隧道施工减灾有一定的借鉴。

| Abstract: | The article based on the analysis and conclusion about some risk assessment theories,in combination with the multilevel fuzzing mathematics theory,the probability model is established about the upslope destruction when the tunnel is constructed.The computation result is substituted to the risk assessment model in combination with the process of risk calculation to create the risk assessment model about tunnel upslope above the opening during the construction period.Eventually,some measures are suggested to manage the upslope risk so as to supply some help to reduce hazard in the tunnel construction. |
