摘要
现行地质勘察规范所制定的围岩工程地质分类法,适用于开工前的设计阶段。结合橙子沟水电站工程引水隧洞施工,具体落实修订规范对地下洞室施工阶段工程地质工作的要求,提出本分类法。本分类法由工程地质分类法提升为地质工程分类法。在橙子沟试用的同时,介绍给同行并征求意见,力求使本分类法在更多的工程实践中接受检验。
The engineering geology classification of surrounding rocks speeified in the existing geological investigation specification is applieable to the design stage before construction. Based on the construction of headrace tunnel for the Chengzigou hydropower project, this engineering geology elassifieation is put forward to meet the requirements on engineering geology at the construction stage of under- ground tunnel as specified in the specification. While used for trial, this classification method is introduced to colleagues for recommen- dations so as to put it into praetiee in more projeets.
