摘要
岩体结构特征研究是硐室稳定性分析的基础,围岩分类实质就是应用工程地质类比法进行围岩稳定性评价。本文根据现场调查结果,对某矿山露天边坡的岩体结构特征进行了分析,并采用国内外通用的RMR和BQ方法进行了岩体质量评价,为边坡岩体稳定性评价提供了依据。
Quality evaluation of engineering rockmass is essentially stability analysis based on engineering geology analogue. As national standard of China, BQ qualification is ubiquitous. However, rockmass with intercalated bed is mechanically unique, ,so it is reasonable to modify Formula BQ in order to match its feature. Taking a slope of a great ore as an example, roekmass structure and quality evaluation is studied.
