摘要
阐述了荣地水电站发电引水隧洞围岩岩体的岩性、岩石强度、结构面产状与状态以及地下水特征,依据规范对围岩进行分类,把初设成果与开挖结果进行对比,指出存在问题,提出建议,为类似工程提供经验。
An introduction was made on the lithology, rock strength, structural plane occurrence and state of the rockmass surrounding diversion tunnel of Rongdi Upgrade Project. The features of underwater are also presented. The surrounding rockmass is classified in accordance with specifications. Based on a comparison between the preliminary design achievements and the excavation exposure, the author presented the existing problems and put forward suggestions to provide engineering reference for similar project.
