本文对比分析了Janssen公式、Ketchum理论、Reimbert计算理论、原方浅仓计算理论,给出了各压力理论适用仓体、优点及局限性。Janssen公式作为现在普遍适用的散体储料压力计算理论,侧压力系数k为一常数的假定与实际情况有一定的出入。不同形状仓体要根据实际情况考虑k值的修正,以达到安全使用的目的。 This paper comparatively analyzes the Janssen formula, Ketchum theory, Reimbert calculation theory and the original square shallow warehouse calculation theory, and gives the application of pressure theory to the warehouse, its advantages and limitations. Janssen formula as a widely applied theory of the calculation of bulk storage pressure, side pressure coefficient k is a constant assumption and the actual situation of a certain discrepancy. Different shape warehouse body according to the actual situation to consider the correction of k value, in order to achieve the purpose of safe use.
