随着深度的增加竖直圆筒容器中的颗粒物质会把自己的重量逐渐转移到容器的侧墙壁上,使容器底部的压力出现不随筒中颗粒材料高度的增加而增加的饱和现象.但值得注意的是,圆筒中的颗粒柱体并不总是表现为这个称为粮仓效应的力学状态.例如当改变侧墙壁的力学环境使其无法承担颗粒的重量时,柱底部的压力显然将随其高度的增加而线性地增加.本文分析讨论了Janssen模型假设对这类处于静力平衡下,但违反粮仓效应的颗粒系统的行为预测.
As the depth increases, the particulate matter in the vertical cylindrical vessel gradually transfers its own weight to the side wall of the vessel, causing the pressure at the bottom of the vessel to become saturated without increasing the height of the particulate material in the cylinder. Is that the cylinder in the cylinder does not always behave as a mechanical state called the granary effect.For example, when changing the mechanical environment of the side wall so that it can not bear the weight of the particle, the pressure at the bottom of the column will obviously vary with its height This paper analyzes and analyzes the behavior prediction of the particle system under the assumption of Janssen model that is under static equilibrium but violating the effect of granary.
