Abstract:

In order to study the transformation and lateral Force in Silo Unloading, this paper simulate a silo unloading flow condition and the stress condition of the wall and the material pressure dis- tribution inside in this condition by the way of discrete element. The result shows that in the con- dition of silo unloading ,the wall dynamic horizontal side pressure is increased than the static. W- ith the particle outflow, the dynamic horizontal pressure of the wall is fluctuating up and down
