Distribution of Lateral Pressure in Large Diameter Squat Silos under Eccentric Discharge
The eccentric discharge of stored solids in squat silos has caused many failures, especially that in metal silos.However, these failures are poorly interpreted by specialists.In particular, the lateral pressure distribution on vertical wall could not be accurately recognized.In order to set out the method to calculate static lateral pressure, the appearance of stored solids in silos after eccentric discharge is researched.In this study, based on the overall balance method (OBM), the method for calculating lateral static pressure in squat silos after eccentric discharge is proposed.Four cases are listed according to different discharge stages.Calculative formulae are deducted for each case.This method is also focusing on unsymmetrical distribution characteristic of the lateral pressure.Two calculative examples are listed and the results of which illustrate the necessity of lateral pressure calculation in squat silos.
