摘要
讨论了钢筋混凝土筒仓仓壁的基本压力及动态压力的确定问题。考虑到筒仓卸料时，仓体内的应力状态及侧压力系数随深度变化的实际情况，建立并求解了微分方程，得出仓壁的动态压力的实用计算公式，并进行相应的筒仓模型试验，测试值与理论计算值基本上相吻合。为钢筋混凝土筒仓的设计和筒仓规范修订提供了理论依据和可靠试验数据。
The calculation method for the dynamic pressure on reinforced concrete silo wall caused by flow of solids during the discharge of storage materials in the silo is discussed in this paper By considering the fact that the coefficients of lateral pressure acting on the silo are varied with its depth,the formula of approximate calculation for checking the theory is presented The calculating results are basically approved by the values of dynamic pressure obtained from the model test of a cylindrical silo
