摘要
针对影响越岭隧道开挖和支护方式的选择的诸多地质因素的不确定性,综合考虑了安全、环保等因素,运用模糊层次性理论,建立了隧道开挖与支护方案选择的多级模糊评判模型,该模型是以单因素赋值,并结合开挖与支护4种类型的评判集来评判;根据层次性递阶结构,建立权重的评判矩阵,并通过一致性检验,以验证模型的可靠性,是一种半定性、半定量的决策方法。并结合雪峰山隧道F8断层开挖与支护方法的选择,实践验证了模型可行性。
This paper aims at the incertitude of geological factors on affecting the choice of excavation and shoring in tunnel through mountain, considers security and environmental protection factors, and uses the theory of fuzzy AHP to establish multi-grade fuzzy evaluation model, which is to evaluate by single factor and judges with four kinds of judging collections of excavation and shoring. According to the structure of hierarchy stepped process, the paper founds the judgment matrix of weight and validates the reliability of model by coherence examination. It is a half qualitative and quantitative decision-making method. The model combines choices of methods of excavation and shoring in the F8 Fault of Xuefenshan tunnel, validates its feasibility by practice, and illuminates its academic and practical value.
