| 摘 要： | 瓦斯突出受诸多不确定性因素影响与控制,其预报是一个复杂的不确定性系统问题。本文应用集对分析理论的多元联系数表达式来定量描述瓦斯突出评价指标样本与评价标准等级之间隶属关系的层次性和模糊性,并用三角模糊数定量表示联系数的差异度系数的连续变化过程,进而通过随机模拟实现把三角模糊数及其函数之间的运算转化为普通实数之间的运算,结合各个评价指标的权重,综合对隧道瓦斯突出进行分析。实例应用表明:该模型应用与隧道瓦斯突出评价是有效可行的,且能提供评价结果的可靠性分析信息。

| Abstract: | Gas burst in tunnel is affected by many uncertain factors,and its prediction is a complex system problem.Based on the set pair analysis and stochastic simulation of triangular fuzzy numbers,a risk analysis model for the gas burst in tunnel was proposed and discussed.A concept of multi-element connection number of the set pair,which was consisted of evaluation index sets and classification standard sets of the gas burst in tunnel,was described to depict the hierarchy and fuzziness of membership between the e... |
