摘要：
The authors analyze the effect revealed at the Institute of Mining, SB RAS in the 1970s. This effect consists in a noticeable off-center displacement of the maximum normal pressure on the bottom of a conical pile when heaped. The new experimental data are presented. The stress-stress analysis of the pile between two parallel smooth plates is solved using a 3D discrete element method. The calculations prove the indicated effect.
