摘要
从细观尺度上分析了砂土类介质两种典型理想单元体内部结构变化对其力学响应的影响；结果表明即使颗粒性质相同，其结构形式（Ｐａｃｋｉｎｇ）不同亦有不同的力学响应．这为砂土扰动效应提供了一种以定量分析为基础的新解释．
The mechanical responses of sand with different packing arrangements were analyzed at meso-sca1e (granule scale), and the results show that there are different responses between stress ratio and volume strain for differeat packs even though the granule in sand is the same. Furthermore, the per- turbation effects of sand could be explained from the quantitative analyses.
