摘要
风险分析是减小岩石公路隧道事故发生率以及灾害损失的重要手段,但是事故资料的不完整性和风险因素的不确定性都给风险分析带来困难。针对岩石公路隧道洞口失稳事故,使用风险分析中常用的专家调查法进行调研,并采用Excel电子表格软件进行数据批量处理,得到洞口失稳事故致险因子的风险等级和重要度排序,并提出了相应的控制方法,可为施工阶段重要风险因素的控制提供参考。
Risk analysis is an important way to reduce the accident rates and loss ot rock highway tunnel. However, the incompletion of accident data and uncertainty of risk factors bring difficulties to risk analysis. In this paper, Specialists method which is widely applied in risk analysis is used to evaluate the risk factors of rock highway tunnel, and the Excel spreadsheet software is used to do the data processing and analysis. Then the risk ranking and importance of risk factors and corresponding control measures are carried out. It is an important basis for further risk analysis and specific measures decision in construction phase of the tunnel.
