| 摘 要： | 本文根据满贮筒仓在卸料过程中贮料作用于仓壁的水平侧压力大大超过贮料静止时的侧压力这一现象,提出在卸料过程中,贮料不断结拱-塌拱-结拱连续循环而生产脉动水平动载超压的观点,导出卸料过程中,贮料作用于仓壁的脉动水平动载超压力的计算公式。

| 关 键 词： | 流速 动力拱 振动周期 惯性力 脉动超压 |

| Abstract: | Based on the phenomenon that the horiz ontal lateral pressure exerted on the wall of the full -silo by the flowing bulk solids is much greater than that exerted by the static ones,a standpoint is proposed that due to the continnous cycle of arch's forming-subsiding-forming in the process of bulk solids discharging,horizontal dynamic pulsative super-pressure is created,a flow velocity -time function is derived,and a formula is obtained to calculate the horizontal dynamic pulsative super - pressure oxtered on the wall of silo by the bulk solids during full-silo discharing. |

| Keywords: | flow velocity dynamic arch vibration period inertial force pulsative super - pressure |
