| 摘 要： | 通过现场实测,研究地铁运行时不同轨道结构的振动特性及减振效果.通过频域分析得到地铁轨道结构的振动情况.结果表明,地铁诱发的振动的垂向加速度总振级比横向加速度总振级大很多,不同的轨道结构从道床到隧道壁的振动衰减有很大不同,因此评价轨道结构的减振效果应主要以隧道壁的垂向振动为主；浮置板轨道的固有频率约为10 Hz,属于低频...

| Abstract: | The realities and mechanism of the vibration induced by the subway with different track structures are studied by in situ experimental method.The analysis of reduction on different tracks is tested respectively in frequency domains.The analysis results suggest that the vertical vibration acceleration is much bigger than the lateral and the vibration transmission of the different tracks from the track bed to the tunnel is different,so damping effect of track structures should be controlled by the vertical vi... |
