| Abstract: | The force transfer in three-dimensional,orderly and symmetrically disposed granular packs was tested and analyzed in detail.The stochastic theory was used to analyzed the test data qualitatively.By the action of axial static load,the downward transfer pattern of the load,distributive configuration of vertically force-transferring particles,and influence of the boundary on them were analyzed,and a stochastic equation of vertical inner-force transfer caused by the combined action of the loads and particles weight was given,also. |
