颗粒堆中轴向静荷载力传递实验分析

Experiment on and analysis of force transfer of axial load in granular packs

对三维有序对称排列的颗粒堆中力传递进行了较为详细的实验与分析,运用随机理论定量分析实验数据,分析在轴向静力荷载作用下荷载力下传规律、力的分布特征及边界效应等因素的影响,并给出了荷载力与颗粒自重共同作用下引起的内力竖向传递的随机方程.

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 giv en, also.
