摘要: 通过室内强化模拟试验,对水布垭心墙堆石坝页岩风化填料的矿物成分、化学成分、颗粒级配的长期稳定性进行了研究。研究结果表明,风化料的矿物成分和化学成分在工程环境中具有较好的长期稳定性;而级配较不稳定,这主要是由其矿物成分及微观结构特征决定。

Abstract: In this paper, through room hardening simulating experiment, a study on weathered shale filler for the Shuibuya project has been performed in the aspects of its mineral compositions, chemical composition, grain composition etc.. The results show that,mineral and chemical composition of weathered stock have better long term stability in engineering environmental condition, but grain composition has worse stability owing to its mineral composition and microcope struture characteristics.
