砂土之液化後不排水殘餘強度為進行液化土層穩定性分析與設計時之重要參數，本研究以渥太華砂與雲母兩種不同顆粒粒徑之土壤為材料，利用濕搗法製作試體，在控制土壤相對密度相同之條件下，進行動態與靜態三軸壓縮試驗，探討低塑性細粒料含量對土壤液化後殘餘強度之影響。研究結果顯示，在相對密度40％情況下，雲母含量在30％前與超過50％後，試體之液化阻抗與液化後殘餘強度隨著雲母含量的增加而降低，而雲母含量30％至50％之間，液化阻抗與液化後殘餘強度隨著雲母含量的增加而增加。此外，比較動態與靜態三軸試驗可發現兩者具有一致性之結果，代表試體經過動態載重其不排水殘餘強度並不會受太大影響。

The undrained residual strength of liquefied sands is an important parameter for stability analysis and engineering design. A series of undrained monotonic and dynamic triaxial compression tests were conducted on reconstituted specimens made of Ottawa sand and mica fines at a constant relative density to study the effects of mica content on residual strength of liquefied sands. Testing results reveal that the liquefaction resistance and undrained residual strength decreases with increasing mica content for mica content less than 30% and more than 50%. For mixtures with mica content between 30% and 50%, the liquefaction resistance and undrained residual strength increases with increasing mica content. In addition, the undrained residual strength of sand-mica mixtures does not significantly affect by dynamic loading prior to initial liquefaction.
