摘要
运营铁路隧道衬砌安全性评定存在诸多定性和定量指标,且这些指标具有不确定性、模糊性和复杂性。为获得较为合理的评定结果,运用模糊数学理论,提出运营铁路隧道衬砌安全性模糊模式识别评价方法。该方法将44个单因素指标划分为4个结构层次,将多层次关系的指标、参数有机地结合起来,较好地处理定性评价指标和定量评价指标之间的关系。计算结果表明:该方法所得评价结果与传统基于经验判断的评价方法所得评价结果相吻合,表明该方法是可靠的。该评价方法充分体现了不同指标在安全性评定中的重要性,可操作性好,弥补了传统基于经验判断的评价方法的不足,对铁路隧道衬砌安全性评价方法的研究具有一定的指导意义。
There are many qualitative and quantitative indices which are of uncertainty,ambiguity and complexity for safety evaluation of operating railway tunnel. In order to obtain a more reasonable evaluation result,the method of fuzzy pattern recognition for the safety of operating railway tunnel lining is proposed. The method that the forty-four indexes are divided into four gradations deals with the relationship between the qualitative evaluation indices and the quantitative evaluation indices. The calculation result shows that the evaluation results obtained by this method coincide with the results by the method of empirical judgments. The method reflects the roles of different indices in the process of various safety evaluation,makes up for the deficiency of traditional method based on empirical judgments,and will have some guidance significance for the further research on safety evaluation of railway tunnel.
