东北某水库坝基岩体质量分级研究

Research on Rock Mass Classification of Dam Foundation of a Reservoir in the Northeast

应用单因素和多因素分类方法,对东北某水库坝基岩体质量进行了分级研究。研究结果表明,除新鲜岩体和微风化岩体外,该区弱风化岩体为良质岩体,经适当处理后,可以考虑作为该水库坝基岩体;而对小部分的弱风化镶嵌结构的岩体,性质较差,需要挖除。

The rock mass of the dam foundation of a reservoir in the Northeast was classified by using the single factor and multiple factor classification methods. The research results showed that most of the weakly weathering rock mass was nice besides fresh rock mass and slightly weathering rock mass, and it may be considered to be rock mass of the dam foundation of the reservoir. The small part of rock mass with weakly weathering structure should be removed due to its poor property.
