| 摘 要： | 在散体直径扩张重力流动实验的基础上,利用虚功原理,导出了深仓状态下的散体侧压公式和垂直平均压力公式 P(H)=(γHρλ_0)/(ρ+Hfλ_0) P_V(H)=(γρ/fλ_0)ln((ρ+Hfλ_0)/ρ) 上述公式结构简单,计算方便,既保留了杨森(Janssen)公式的基本优点,又克服了其理论上的缺陷。

| Abstract: | Based on the diameter expanding experiments and using the principle of virtual work, the new equation for calculating pressure on deep storehouse wall and mean pressure at the bottom had been developed:The above equation are convenient for calculating, they hold the major superiority of Janssen and overcame its defaults on theory. |
