摘要
对受集中荷载作用的三维颗粒堆中力的传递与分布进行了实验,对其结果进行半定量统计分析,研究了有序对称密实排列颗粒堆中力的传递特征、压痕与压力的关系、颗粒堆传力不均匀性及荷载力概率密度的变化规律,并解释了抛物型曲面传导的原因．
The paper investigates the distribution of contact forces in a three-dimensional granular pile submitted to a compressive load, makes a half-quantitative analysis of the statistics, analyzes the transferred character and the relation between impresses and the pressure, and changes the rule of the asymmetric degree and probability density. Moreover, the reason for the conduction of the Daraboloid type is explained.
