水布垭页岩风化料长期稳定性试验研究

摘要

In this paper,through room hardening simulating experiment,a study on weat hered shale filler for the Shuibuya project has been performed in the aspects o f its m ineral 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 characteristi cs.%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。
