摘要
隧道围岩分级是正确进行隧道设计与施工的基础。采用规范规定的围岩分级方法,根据岩石强度程度、岩体完整程度两个基本因素进行初步分级,提出高水压下围岩级别的修正,为隧道结构设计与施工提供合理参数。
The classification of tunnel surrounding rock is the foundation of tunnel design and construction. Based on the code prescriptive method, preliminary classification of tunnel surrounding rock is conducted according to the two basic factors of rock strength degree and rock integrity degree. A modified classification of tunnel surrounding rock under high water pressure is suggested, which can provide rational parameters for tunnel design and construction.
