摘　　要：采用总体平衡方法给出了一个新的大直径浅圆仓散体静态侧压力计算公式,该公式计算简单,并可用于储料顶部为平顶和锥顶两种情况。本文公式的计算结果经与实仓测试结果、国家规范和库仑公式对比分析表明,本文公式的计算结果与实仓测试结果吻合良好,本文公式的计算精度和吻合趋势好于国家规范和库仑公式。A new formula for calculating lateral static pressure on shallow silo wall is derived by global equilibrium method. The formula of this paper is simple for calculation and can be used for silos with different materiel shape on the top. The formula of this paper is applied to calculate the lateral pressure on the wall of the real wheat silo. The calculated results of this formula are compared with results of real experiments, Chinese design code for silo and Coulomb formula. It is shown that the calculated results of this formula are good in agreement with real experiments, and its accuracy is better than Chinese design code for silo and Coulomb formula.
