| 摘 要： | 工程岩体质量评价实质就是应用工程地质类比法进行围岩稳定性评价。BQ分类作为国标，具有普适性。针对含软弱夹层岩体的力学特性，探讨了如何以BQ分类为基础，经过适当修正以建立合适的围岩质量评价体系。结合西南某大型水电站地下厂房区围岩岩体结构特征，进行了洞室围岩质量评价，其结果与RMR分类系统判别结果基本一致。

| Abstract: | 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 underground cavities of a large hydropower station in Southwest China for example, rockmass structure and quality evaluation are studied. The result agrees basically with the one acquired by RMR System. |
