摘要
在分析隧道围岩分类方法的基础上,确定多因素单指标的围岩类别等级标准,根据灰色系统关联度理论对围岩等级进行判别,科学合理的进行等级划分,对隧洞围岩进行稳定性评价具有很好的借鉴意义。
Basing on the analysis of tunnel rock classification method, the rock types grade standards of multi-factor single indi- cator is determined, the rock types are graded and scientifically classified with gray correlative theory, which gives a reference for rock stability evaluation of tunnel.
