摘要
利用库仑(Koulomb)主动土压力理论,采用极限平衡计算方法确定浅圆仓散料的破裂面,计算浅圆仓散料对仓壁的侧压力,并对不同工况进行详细分析,明确了不同工况的简明判断条件,计算公式的适用范围。补充了我国现行的《钢筋混凝土筒仓设计规范》关于大直径浅圆仓散料侧压力计算的相关内容,可供工程设计参考使用。
Based on the Coulomb＇s earth-pressure theory, the failure plane of bulk solid in squat silos was obtained with the limit equilibrium method, and then, the wall pressure was calculated .According to detailed analysis under different conditions, this paper put forward the simple criterion to distinguish these conditions and the corresponding calculation formula, which provides supplementations to the Code for design of reinforced concrete silos. Moreover, this research provides useful references for engineering design.
