摘　　要：通过对不同袋内材料的土工袋及相应的袋内材料进行竖向减振效果激振试验,对比分析其最大加速度衰减率及频响函数,并探讨了不同层数及不同排列方式的土工袋组合体对竖向减振效果的影响。试验结果表明,加速度衰减大多集中于顶部三层土工袋内,且土工袋交错排列的减振效果较成列排列更好。A series of excitation tests are comparatively carried out on soilbags filled with different soils and on the inside soils to study their vertical damping effects. Based on the analysis of maximum acceleration attenuation rate and frequency response function, the influence of soilbag arrangements and layers on the vertical damping effects is investigated. The test results show that the top three layers of soilbags plays a major role on acceleration attenuation, and the staggered arrangement of soilbags has better damping effect than those of column arrangement.
