Several problems should be noted in surrounding rock classification of railway tunnel in the loess region

通过太中银铁路的工程实践,结合现有铁路隧道确定围岩分级的方法,提出了在西北黄土地区铁路隧道勘察中应特别注意的几个问题,以确保围岩分级合理,工程保质保量按期完成。

Through the engineering practice of Tai-Zhong-Yin railway, combined with determining railway tunnel surrounding classified method, several problems need be noted specially in railway tunnel investigation in northwest China loess region were proposed, so as to guarantee surrounding classification rational and engineering was finished with guaranteeing quality.
