Three-dimensional seismic isolation system for buildings built above the subway

Abstract

The invention discloses a three-dimensional seismic isolation system for a building built above a subway, comprising a superstructure, a seismic isolation layer and a lower structure, the lower structure is arranged on the subway, an external building is covered on the superstructure, and the seismic isolation The layers are arranged on the substructure, and the superstructure is mounted on an isolation layer comprising several laminated rubber bearings and several viscous dampers. The three-dimensional seismic isolation system for the building above the subway of the present invention can isolate the lateral vibration through the laminated rubber bearing by setting the seismic isolation layer as a combination of the laminated rubber bearing and the viscous damper, and through the viscous The damper isolates the vertical vibration, thus effectively realizing the effect of seismically isolating the superstructure and the subway.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a three-dimensional shock-isolation system for a building built above a subway. Background technique [0002] With the increase of the mileage of my country's subway lines, the vibration and noise reduction of the subway, especially the buildings above the subway, is becoming more and more important. The complaints from the owners and the improvement of the quality of life have gradually transformed the technical problem of noise into a problem of people's livelihood, and even a political problem, which has attracted much attention from the society. For subway superstructure, adjacency, and cross-construction projects, the operation of the subway will have adverse effects on the buildings. It is necessary to isolate the vibration of the subway superstructure. Generally, a vibration isolation layer is required, and rubber shock absorbers are often used to reduce vibration. I...

Problems solved by technology

For subway superstructure, adjacency, and cross-construction projects, the operation of the subway will have adverse effects on the buildings. It is necessary to isolate the vibration of the subway superstructure. Generally, a vibration isolation layer is required, and rubber shock absorbers are often used to reduce vibration. It can only isolate the horizontal seismic action, but not the vertical seismic action and subway vibration
