为了解决隧道施工中存在的大量随机性和模糊性问题,提出了一种带置信因子的模糊评价方法,建立的基于置信因子的在建隧道模糊评价模型,用于科学地定量确认危害产生原因;通过确定置信因子和建立模糊综合评价信度,补偿评价中主观信度,实现危险控制过程。应用实例证明该方法是有效,可行和可靠的,具有实际推广价值。%In order to solve many problems of randomness and fuzziness in the tunnel construction,the paper points out the fuzzy evaluation method based on the confidence factors,establishes the fuzzy evaluation models for the building tunnels based on the confidence factors,has the quantitative identification of the reasons by the hazards in a scientific way,the hazard control process can be realized by identifying the confidence factors,establishing the fuzzy comprehensive evaluation reliability,and supplementing the subjective reliability,and proves by the examples that the method is effective,feasible and reliable,so it has the factual value for further application.
