摘要
铁路隧道围岩级别的划分是指导隧道设计和施工的重要依据 ,目前在设计和施工中对隧道围岩级别的判定方法具有较多的经验性因素。本文引入模糊信息的概念 ,以大量既有隧道围岩分级的信息提取为基础 ,建立了隧道围岩分级的模糊信息分析模型 ,其中应用层次分析方法 ,确定各个影响因素在围岩分级中的权重分配。通过工程实践应用 ,取得了良好效果。
Tunnel surrounding rockmass classification is important basis of design and construction. Now, there are more experience factors in tunnel surrounding rockmass classification at design and construction. In present paper, the concept of fuzzy information is brought in. Based on picking up information from a large number of actual examples, classification model is set up with fuzzy information analysis technique. At the same time, sequence analysis method is used to ascertain weightiness of every factor in the classification. This model is testified having good effect in actual surrounding rockmass classification.
