Embodiment 1

[0048] This embodiment provides a vibration isolation system. The vibration isolation system is installed between the subgrade and a target building foundation such as figure 1 shown. Further, a multi-level vibration isolation base structure is constructed between the base layer and a target building base layer. The multi-stage vibration-isolation foundation structure includes a vibration-damping foundation layer 4 and a first bottom cushion layer 1 . On the one hand, the multi-stage vibration isolation foundation structure can absorb vibrations through the joint action of the first base layer 1 and the vibration-damping foundation layer 4, thereby providing a sufficiently good vibration-suppression effect for the target foundation layer 300; The base layer 4 provides a balanced supporting force for the target base layer 300, thereby producing an effective anti-uniform settlement effect.

[0049] In this embodiment, the vibration-damping foundation layer 4 is spread horizon...

Embodiment 2

[0061] The structure of the vibration isolation system provided in this embodiment is basically the same as that of the vibration isolation system described in Embodiment 1, and the similarities will not be repeated. The difference is that the vibration isolation system of this embodiment is installed Between building base layers, such as image 3 shown. Since there are multiple target base layers 300 in this embodiment, the bottom of each target base layer 300 is wrapped with a first base layer 1 , and each first base layer 1 is connected to the same vibration-damping base layer 4 .

[0062] It can be understood that since different buildings or multiple target base layers 300 of the same building are independent of each other, uneven settlement is easily generated when affected by vibration, so it is preferred that this embodiment preferably adopts a large-area raft foundation as a vibration damping The base layer 4 uses the vibration-absorbing base layer 4 to connect a plu...

Embodiment 3

[0067] Based on the structure of the vibration isolation system described in Embodiment 1 or Embodiment 2, this embodiment provides another vibration isolation system. The structure of the vibration isolation system is the same as the structure of the vibration isolation system described in Embodiment 1 or Embodiment 2. The difference is that the vibration damping base layer 4 of the vibration isolation system described in this embodiment includes One or more horizontal base unit panels stacked vertically. When there are multiple basic unit boards, a second base layer 2 is installed between two adjacent basic unit boards up and down. The vertical vibration time history Z of the vibration source 0When passing through a plurality of horizontally placed basic unit plates, it is decomposed and consumed step by step by a plurality of second bottom cushion layers 2 arranged in sequence, so as to upgrade the original two-stage vibration damping effect to more than two-stage vibratio...

Abstract

The invention relates to the technical field of building vibration reduction structures, in particular to a settling-resistant vibration isolation system, a vibration reduction method, a building, anda vibration isolation effect detecting method. The settling-resistant vibration isolation system comprises a multi-stage vibration isolation basic structure arranged between a foundation layer and one or more target basic layers; and the multi-stage vibration isolation basic structure comprises a vibration reduction basic layer arranged between the bottom foundation layer and all the target basiclayers, and first bottom mat layers arranged between all the target basic layers and the vibration reduction basic layer correspondingly. The vibration isolation system can achieve the good enough vibration suppression effect which cannot be achieved by an existing single-stage vibration isolation structure, and the effective effect of resisting uneven settling is generated through the multi-stage vibration isolation basic structure; and the vibration isolation system can effectively relieve the vibration influence caused by rail traffic operation on the building, and can further improve thecapacity of the building for resisting uneven settling.

Description

technical field [0001] The invention relates to the technical field of building vibration-damping structures, in particular to an anti-subsidence vibration-isolation system, a vibration-damping method, a building, and a method for detecting vibration-isolation effects. Background technique [0002] Under the background of exponential growth of urban rail transit operation mileage and continuous densification and expansion of the network scale, rail transit lines and existing or newly built construction sites inevitably overlap, and even pass through special buildings with dangerous sources . The vibration generated by the wheel-rail action is transmitted to the building foundation through the tunnel structure and rock-soil medium, causing a decrease in the living comfort of the building and failure of vibration-sensitive equipment, etc. The impact of secondary radiation noise caused by floor and wall vibrations further aggravates vibration pollution. influences.
