Based on the micro mechanical feature of materials and the strength theory of fibrous bunchiness, the macro statistical size effect of materials was gained.
从材料的微观力学性质入手，用纤维束强度理论，得到了材料的宏观统计力学效应。

The research indicates that different sizes of specimens result in different values of soil shear strength, and this phenomenon can be well explained using the strength theory of fibrous bunchiness.
