摘要
将无底筒仓内填料分为主动区和被动区,分别对两个区建立力平衡方程,根据筒顶和筒底应力边界条件分别求出两个微分方程的解。未知的筒底应力边界条件,通过迭代法确定,建立了无底筒仓内填抖压力的一种计算方法,并与模型试验结果进行了比较。
The filler in an open-ended silo is divided into two parts: active part and passive part. Two force equilibrium equations are setup respectively for them. The answers to the two equations, respectively meeting the top and the bottom boundary conditions, are obtained. The unknown bottom, stress boundary condition can be determined by the iterative formulae given herein. The approach is verified through model experimental data.
