摘　　要：通过对巴塘水电站主体工程开挖料进行物理性能、碱活性、云母含量及混凝土配合比、力学性能等试验,得出主体工程开挖料弱风化以下黑云母石英片岩满足相关规范各项指标要求,可以作为混凝土骨料、大坝过渡料及反滤料的结论,并据此对料场、渣场、砂石混凝土加工系统布置进行调整,大大降低了工程投资,提高了巴塘水电站的经济性。Tests on physical properties,alkali activity,mica content,concrete mix ratio,and mechanical properties of excavated material of the main project of Batang hydropower Station show that black mica-quartzose schist below weak-weathered rock meets the requirement of relevant specifications,and it can be used as concrete aggregates,filling-material for dam transition area and cushion materials.Based on this,the author proposes adjustment of the layout of material yards,spoil yard,and concrete batching system,which remarkably reduces the investment and improves the economy of the project.
