摘 要: 考虑隧道与地下工程地质条件的复杂性和不确定性,将评价指标的取值扩展为一个概率区间,提出一种改进的属性区间识别方法,从单指标属性测度分析、多指标属性测度分析和属性识别分析3个方面,对该方法进行探讨,并提出多指标属性测度计算方法及其对应的属性识别分析方法。以湖北省三峡翻坝高速鸡公岭隧道、宜巴高速公路峡口隧道为例,运用本文方法对其突水风险进行评估。研究结果表明:本文方法突水风险评估结果与工程实际情况较吻合,验证了方法的可行性。与模糊数学、属性数学等其他方法相比,本文方法所得的风险等级更明确,可为隧道与地下工程地质灾害风险评价提供参考。

Abstract:Considering the complexity and uncertainty of geological conditions of tunnels and underground engineering, the value of evaluation index was extended to a probability interval, and an improved attribute interval recognition method was proposed. From three aspects of single index attribute measure analysis, multi-index attribute measure analysis and attribute recognition analysis, this method was discussed systematically and the calculation methods of the multi-index attribute measure and attribute recognition were proposed. The risks of water inrush disasters in Jigongling Tunnel at Three Gorges Dam Expressway and Xiakou Tunnel of Yiba Expressway in Hubei Province were studied as cases using the proposed method. The results show that evaluation results from the proposed method are in good agreement with the actual engineering situation, which verifies the feasibility of the method. Compared with other methods, such as fuzzy mathematic and attribute mathematic, the risk level obtained by the proposed method is more explicit, which provides reference for risk assessment of geohazards in tunnels and underground engineering.
