摘要
在深仓散体静压理论研究￣［１］的基础上，作者根据筒仓卸料时动态拱下存在自由下落区这一客观事实，建立了整体流态下大高径比筒仓动压近似分布理论。其中，最大动压为该理论推导容易，计算方便且预测精度高，特别是工程上最关注的Ｐ＿（ｍａｘ）值与实测值对照，误差小于１０％。另外，本文还就一些重要实验现象给予了合理的理论解释。
In this paper,based on the study on static pressure theory of bulk solid in silos,the new theory of pressure distribution of mass flow behavior(H/D≥3)has been developed in ac-cordance with the fact that a free-falling area exists under the dynamic arch.The maximumdynamic pressure is It is convenient to calculate and the calculated values approximate to the measured ones,es-pecially the error of P_(max)(H)is about 10%.In addition,the reasonable explanations of some experiment phenomena have been also giv-en in this paper.
