摘　　要：钢筋混凝土筒仓装满粮食后要承受粮食对仓体结构巨大的荷载.诸多学者研究表明, 人们已经能确定, 当粮食以底部卸料的形式从筒仓中流出时, 对筒仓的压力作用更大.而粮食出仓过程中在筒仓内部的流态与压力有密切关系.本文借助计算机模拟软件对粮食出仓全过程进行数值模拟, 观察粮食的位移情况, 分析得出粮食出仓时的流态变化.When the reinforced concrete silos are filled with grain, they have to bear the huge load of grain on the warehouse structure. After research, people have been able to determine that when grain is discharged from silos in the form of bottom unloading, the pressure on silos is even greater. The flow pattern and pressure in silos are closely related to grain storage. In this paper, the whole process of grain warehouse was simulated with the aid of computer simulation software, the displacement of grain was observed, and the change of the flow pattern when grain was out of the warehouse was analyzed.
