Silo's Static and Dynamic Testing Study on Considering the Interaction of Foundation, Structure and Bulk Solid——[1] Static and Dynamic Testing Study

对贮仓结构的静、动力问题进行了系统的实验研究 :考虑到地基———结构———散粒体的相互作用 ,设计并完成了不同地基上的筒仓模型的静、动力试验 (包括模型制作、试验和测试方案 ,数据输入输出及处理 )。根据对多种工况试验的观察 ,得出结论 :在地基水平振动的情况下 ,贮仓内绝大部分的散粒体与仓壁没有相对运动 。

A systematic testing study on the silo's static and dynamic projects is made by the authors. Considering interaction among foundation, structure and bulk solid, a static and dynamic test on silo models is designed and completed. The test includes models preparing, establishing plan of experiment and test, data input/output and treatment. On observing test results for different operating modes, the authors found the conclusion that there are no relative motions between the most bulk solids and silo wall when the foundation has a horizontal vibration, just only a little bulk solids leave the silo wall and may have relative motions with the silo wall.
