隧道洞口滑坡体风险分析

摘要

以某滑坡体边缘隧道洞口失稳风险评估为例,介绍一种具有实际意义的隧道风险评估方法:首先采用层次分析法对风险事件中的风险源进行重要性排序,然后结合数值模拟、模糊综合评价法确定风险事件的风险等级.基于此,提出进一步的风险控制措施,以保证风险评估的可靠性.%With instability risk analysis of tunnel exit at the edge of certain landslide body was studied as example,this paper introduced a practical tunnel risk evaluation method: Firstly,AHP is used to sort the risk sources in risk events,and then the risk level of risk events is determined by numerical simulation and fuzzy comprehensive evaluation.Upon this basis,further risk control measures were suggested to guarantee the reliability of the risk evaluation.
