Vibration isolation structure suitable for corridor basement and construction method of vibration isolation structure
The invention relates to the field of constructional engineering, and discloses a vibration isolation structure suitable for a corridor basement, the vibration isolation structure comprises a basement structure and a basement corridor arranged on one side of the basement structure, an anti-vibration expansion joint exists between the basement corridor and the basement structure, and a high-damping vibration isolation material layer is laid at the bottom of the basement corridor; the subway tunnel is arranged below the high-damping vibration isolation material layer, an energy absorption barrier is arranged between the subway tunnel and the basement structure, the energy absorption barrier exceeds the bottom elevation of the subway tunnel and extends to the intermediate weathered rock stratum, and the energy absorption barrier is composed of a rigid barrier body and a flexible barrier body. By arranging the rigid barrier and the flexible barrier, vibration propagation from the tunnel to a side soil body to an adjacent building is reduced, an area adjacent to a subway is reinforced, the influence of excavation of the flexible barrier or a basement foundation pit on an operation tunnel is reduced, and construction safety is guaranteed; and vibration propagation from the tunnel to a side soil body and then to an adjacent building is reduced.
本发明涉及建筑工程领域，且公开了一种适用于连廊地下室的隔振结构，包括地下室结构以及设置在地下室结构一侧的地下室连廊，地下室连廊与地下室结构之间存在有抗振伸缩缝，地下室连廊的底部铺设有高阻尼隔振材料层，地铁隧道设置在高阻尼隔振材料层下方，地铁隧道与地下室结构之间设置有吸能屏障，吸能屏障超过地铁隧道底标高并延伸至中风化岩层，吸能屏障由刚性屏障以及柔性屏障组成，通过设置了刚性屏障，减少从隧道到侧面土体再到临近建筑物的振动传播，为临近地铁区域加固，减少柔性屏障或地下室基坑开挖对运营隧道的影响，保证施工安全，通过设置了柔性屏障，其与刚性屏障形成一道双屏障，减少从隧道到侧面土体再到临近建筑物的振动传播。
