Abstract:	本文先假設土壤剪力面的粒間摩擦力的剪應力等於粒間的動態摩擦力。然後，依據物理學對兩物體間動摩擦力及動摩擦力定律的定義；推論土體在控制其他變因條件狀態的剪力面，存在符合統計學常態分佈的動摩擦角，可代表該土體的剪應力本質。假設相同土壤粒子群在適當控制其他變因的試驗條件下，存在符合常態分佈的動摩擦角。本研究以統計學的「試驗設計」觀念，設計求動摩擦角母體的試驗：取相同的土壤粒子群材料，以應變式直接剪力試驗針對不同垂直應力，依正常壓密態動摩擦角與破壞剪應力、正向應力之關係得到大於40組的動摩擦角母體。依統計學驗證相 This paper assumes that the shear stress of the interparticle friction equals to interparticle kinetic friction on a shear plane of a soil. Laboratory experiments were conducted based on the friction law of physics, the kinetic friction angle of two solid
