對於顆粒性土壤而言，雲母細粒料含量對於極限狀態參數的影響探討還不是很完整。因此，本研究利用渥太華砂與不同雲母細粒料含量，以濕搗法進行一連串的三軸壓縮試驗，並以試驗結果來探討雲母細粒料含量對於顆粒性土壤之極限狀態參數影響。實驗結果顯示，對於極限狀態參數Г、λ、M、κ、Ν而言，Г、κ、Ν在雲母含量低於25%時，其值會隨著雲母細粒料含量增加而降低，在雲母細粒料含量高於25%時，則會隨著雲母細粒料含量的增加而增加；λ則是會隨著雲母細粒料含量的增加而增加；而M則是會隨著雲母細粒料含量的增加而降低。

For granular soils, the effects of mica fines content on critical state parameters is not very complete. This research uses the Ottawa sands with the different mica fines content by moisture tamping method to perform the triaxial compression test, and use the experimental result to study the effects of mica fines content on critical state parameters of granular soils.The experimental results showed that for the critical state parameters Γ、λ 、 M、κ and Ν when the mica fines content is lower than 25%, the value of Γ、κ and Ν will reduce with mica fines content; When mica fines content is higher than 25%, the value of Γ、κ and Ν will increase with mica fines content; The value of λ will increase with mica fines content, but the value of M will reduce with mica fines content.
