隧洞围岩如何分级（或称分类）,才能满足TBM施工条件下的隧洞施工需要,是一值得研究的问题。结合大伙房输水工程对TBM施工条件下的隧洞围岩分级,主要针对工程岩体的可掘进性进行研究,并在此基础上进行支护结构设计,这对TBM隧洞围岩的分级方法进一步研究和TBM隧洞施工都有利。
隧洞圍巖如何分級（或稱分類）,纔能滿足TBM施工條件下的隧洞施工需要,是一值得研究的問題。結閤大夥房輸水工程對TBM施工條件下的隧洞圍巖分級,主要針對工程巖體的可掘進性進行研究,併在此基礎上進行支護結構設計,這對TBM隧洞圍巖的分級方法進一步研究和TBM隧洞施工都有利。

How to classify （or group） tunnel surrounding rock to meet the requirement of TBM construction is worth to be studied. The article, combined with the tunnel surrounding rock classification under TBM construction condition in Dahuofang water conveyance project, studies the boreability of the surrounding rock mainly, and then bases on this to carry out the support structure design, which are in favor of further study on tunnel surrounding rock classification and TBM construction.
