摘　　要：铁路隧道围岩分级研究在我国展开试验研究最早且较为系统深入,对我国地下工程围岩分级方法的发展颇有影响。本文着重介绍了从上世纪60年代至本世纪初3个阶段铁路隧道围岩分级的发展。从过去的定性划分为主逐步过渡到当前的以定性为主,辅以岩石强度、岩体纵波强度等量化指标的新分级方法向国家标准化《工程岩体分级标准》靠拢,将围岩类别改为围岩级别,序次上颠倒成Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ、Ⅵ级。The experimental study of the railroad tunnel wall rock classification research in our country is early and researched systematiclly.It made quite influential to our country underground project wall rock classifica- tion method development.This article introduced the third stage railway tunnel wall rock classification devel- opment from on century 60′s to this century.Primarily gradually from the past qualitative division to cur- rently by qualitative primarily,auxiliary by the rock intensity,the rock longitudinal wave intensity isometric new classification method'Engineering Rock Classification Standard'closed up to the national standardiza- tion,changes wall rock sort to the classification.On the order inverts Ⅰ,Ⅱ,Ⅲ,Ⅳ,Ⅴ,Ⅵ level.
