Vibration reduction and isolation structure for subway station
The invention relates to the technical field of rail transit vibration reduction, and discloses a vibration reduction and isolation structure for a subway station, which comprises a first reinforced concrete wall, a second reinforced concrete wall and a vibration isolation layer, the vibration isolation layer and the second reinforced concrete wall are sequentially arranged on the side, away from the subway tunnel, of the first reinforced concrete wall, and the bottom face of the second reinforced concrete wall downwards protrudes out of the bottom face of a track plate of the subway tunnel by at least two meters. According to the vibration reduction and isolation structure for the metro station, the first reinforced concrete wall, the vibration isolation layer and the second reinforced concrete wall are sequentially arranged on the side portion of the metro tunnel, the bottom face of the second reinforced concrete wall downwards protrudes out of the bottom face of the track plate of the metro tunnel by at least two meters, and therefore vibration waves are weakened by the vibration isolation layer when being transmitted; and then diffraction is needed from the bottom of the second reinforced concrete wall, so that a low-frequency vibration amplification area is farther, and the influence of rail transit vibration on nearby buildings is reduced.
本发明涉及轨道交通减振技术领域，公开了一种用于地铁场站的减振隔振结构，包括第一钢筋混凝土墙、第二钢筋混凝土墙和隔振层，第一钢筋混凝土墙位于地铁隧道的侧部，隔振层、第二钢筋混凝土墙依次设于第一钢筋混凝土墙背离地铁隧道的一侧，第二钢筋混凝土墙的底面向下凸出于地铁隧道的轨道板底面至少2米。本发明的用于地铁场站的减振隔振结构，通过在地铁隧道的侧部依次设置第一钢筋混凝土墙、隔振层、第二钢筋混凝土墙，第二钢筋混凝土墙的底面向下凸出于地铁隧道的轨道板底面至少2米，从而振动波传导时先被隔振层减弱，然后需要从第二钢筋混凝土墙的底部绕射，使得低频振动放大区更远，减轻了轨道交通振动对附近建筑物的影响。
