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。 In order to study the damping effect of geotextile bags, the vibration test was carried out by comparing the damping effect of geotextile bags and the natural river sands in bags with different frequencies and different vibration accelerations. The comparison of the response of the top mass to acceleration and geotechnical Acceleration of bag reaction. The experimental results show that the damping effect of geotextile bags is much better than that of natural river sand when the vibration frequency is large, and the greater the input vibration acceleration is, the better geotextile damping effect is.
