摘要
根据杨森(Janssen)公式的推导思路,提出了一个筒中筒仓贮料侧压力的计算公式。按照某实物仓的1/52比例,制做了一个有机玻璃模型,做了100多次装料、卸料试验。分析计算与实验结果表明,筒中筒仓的贮料侧压力较单筒筒仓时显著降低。这一结果对于这种新型筒中筒仓的设计研究具有很重要的意义。
On the thought of Janssen's theory, a formula for calculating the stored materialpressures of silo in silo is deduced; A plexiglass model that is one fifty-second of a realsilo is made. Hundreds of experiments for loading and unloading conditions aredone. The results of calculation and experiments show that the stored material lateralpressures of silo in silo are evidently less than that of the seimple silo. This is very signifi-cant in the design and study of the new type of silo in silo.
