| Abstract: | A method for the Pressure calculation in silos is Proposed in the paper. It is based on a new concept that is the character istic index of pressures. We find that the lateral and the normal pressure coefficients can get from the characteristic index of Pressures. What is more, the Pressure distribution in silos is varied with the characteristic index of Pressure, So, We establish a unified theory for the Pressure calculation in hoppers and cylinders. The calculating results are more agreed with that of the model tests. The research achievement is practical and purposeful for the silo design. |
