| 摘 要： | 设计了一个土壤介质振动传递试验模型,测量得到了振动加速度响应随距离、激励力大小以及激励频率的变化规律。试验结果表明,响应随距离的增大而减小,随激励力的增大而增大,随激励频率的增大而增大。同时对北京地铁十三号线太阳园段进行振动测量,实际测量结果与模型实验测量结果对比分析表明,土壤介质振动传递试验模型可以很好的反应轨道交通振动的传递特性。 |

| Abstract: | A test model is presented to simulate the train-induced ground-surface vibrations. The relationships between the dynamic response and the distance, exciting force and excitation frequency are analyzed. The results show that the responses decreases with increasing of the distance, but increases with the increase of exciting force and excitation frequency. As the same time we carried out vibration test along the Beijing metro line 13 and we acquired the regulation of the transfer characteristics. In addition the results show that the test model designed could well simulated the railway vibration. |
