| 摘 要： | 本在计算地基运动时筒仓的动力响应时，考虑了仓内散粒体与仓壁的相互作用对其的影响，根据实验观测的现象，将仓内上部占总质量20％－30％的散粒体处理为几个集中质量并将其分别与仓壁均匀弹性连续（弹性杆只承受压力而不承受拉力），分析地基运动时筒仓的动力响应（仓壁位移植）并与筒仓模型实测值进行了比较，两结果吻合较好。

| Abstract: | This paper calculates the silo's dynamic response when foundation moves, taking into account the effect of interaction between the bulk solid and the silo wall. Based on the phenomena observed in the experiments conducted by the author and other researchers, it is supposed that the bulk solid in the upper part of the silo, which makes up about 20%~30% of the total mass, is equivalent into several concentrated masses. Furthermore, each concentrated mass is uniformly connected to the silo wall through elastic bars, which can only bear compressive force instead of tensile force. The calculated dynamic response (i.e. displacements of the silo wall) when foundation moves is compared with the experimental result, showing a good agreement between the two. |
