摘要
本文概要记述作用于模型筒仓仓壁的静态压力及由物料流动引起仓壁动态压力的多次测试结果,并绘出仓壁的动压力分布曲线,得出相应的超压系数,为“钢筋混凝土筒仓设计规范”提供必要的试验数据。同时并进行了动态压力的理论分析和数值计算,其结果与试验值基本接近。
In this article,the test results of statical lateral pressure and dynamicallateral pressure caused by the flow of store material to the wall of silo arebriefly described. The distribution curve of dynamical lateral pressure alongthe height of the silo wall is plotted. The relevant over-pressure coefficientis obtained and the necessary experimental data are provided for 'DesignStandard for Reinforced Concrete Silos'. Meanwhile, a theoritical analysis ismade of dynamical pressure and numerial calculation is worked out, whichalmost agree with the test results obtained.
