本文在分析国内外几种岩体分类系统的基础上,综合了影响岩体稳定性的主要因素,通过计算和比较开挖岩体与分类系统中各岩体类级的贴近度,确定开挖岩体的类级。
Based on the analysis of several rock mass classification systems both at home and abroad, this paper synthesizes the main factors that affect the stability of rock mass. By calculating and comparing the close degree of each rock mass class in rock mass and classification system, Class of rock mass.
