Summary:	本研究主要探討膠結顆粒材料之微觀結構型態(膠結顆粒之粒徑組成、排列型態)對於整體顆粒材料集合體之宏觀力學的影響。試驗以平面應變試驗為主，採用圓型鋁棒作為基本顆粒，針對不同微觀結構(排列、粒徑分佈)探討其強度及變形性之變化。為瞭解整體變形場之變化，試驗過程中使用數位影像相關係數法分析試體之全域應變場的分布。經平面應變試驗及應變分析結果顯示：(1) 不同粒徑的顆粒所組成之試體其強度較單一粒徑、緊密排列之試體為低。(2) 單一粒徑組成有膠結，但顆粒直徑不同之試體，在強度上無明顯差異。(3) 從同樣為有膠結隨機排列，但顆粒之幾何形狀不同的圓鋁棒試體和橢圓鋁棒試體結果來看，圓鋁棒試體之摩擦角會比橢圓鋁棒試體之摩擦角來的高。 This study explored the influence of microscopic parameters (particle size, packing type, shape of particle) of the cemented granular material on the macroscopic behaviors. A series of plane strain tests were performed in this study. The results of the plane strain test exhibit the following characteristics: (A) The strength of specimens with unique particle sizes is higher than that with different particle sizes. (B) In the same unit diameter and cohesive specimens, the strength of the results do not have obvious differences in different diameters of specimens. (C) In the same condition, comparing the friction angle of circle particle with the friction angle of ellipse particle, this study show that the front one is higher than the other one.
