【摘要】 为研究土工袋的减振效果,在振动台上通过对土工袋及其袋内材料天然河砂减振效果输入不同频率、不同振动加速度进行对比试验,对比分析了其顶部质量块响应加速度和土工袋层间加速度反应情况。试验结果表明,当振动台台面振动频率较大时土工袋的减振效果明显优于袋内材料天然河砂的减振效果,且输入振动加速度越大土工袋的减振效果越好。更多还原

【Abstract】 In order to study the vibration reduction effect of soil bag,a series of vibrating platform tests are comparatively carried out on soil bag filled with river sand under different vibration frequencies and different accelerations.Through analysis of the response accelerations of the upper mass block and the interlayer accelerations,the results show that when the vibration frequency of vibrating platform is high,the vibration reduction effect of soil bag is better than that filled with river sand;input vibration acceleration is greater,the soil bag has better vibration reduction effect.更多还原
