At present, with the rapid development of subway transportation systems, rail transit also affects buildings and residents around the line while bearing the urban transportation task. Vibration has also become one of the most widely recognized public hazards, and can not only affect and damage transportation, buildings and equipment, but also directly cause injury to human bodies.
For the structural vibration mainly in the vertical direction caused by the rail transit, the current vibration isolation control method mainly takes vibration source control (such as adopting a floating slab rail) and propagation process control (such as excavating a vibration isolation trench) as main components. But if the building is too close to the subway or the two methods are difficult to adopt due to objective reasons, vibration damping control measures of the vibration receiving body are needed.
However, the vibration damping method of the vibration receiving body itself is less researched, and some scholars propose some vibration damping measures and methods, but no examples of effective application in actual engineering are presented. Devices or technologies for effectively reducing rail transit vibration of the vibration receiving body are yet to be developed and researched.
Although the existing three-dimensional shock insulation and vibration reduction device realizes the three-dimensional shock insulation and vibration reduction effect to a certain extent, the shock insulation effect is provided by a support only in many times, and the effect of isolating horizontal earthquake is not needed; meanwhile, for different building structures, the bearing force of the columns is different, and if the stiffness of the columns is the same after the vibration isolation support is added, the compression amount of the butterfly spring is different, so that the vibration isolation support is required to have a height adjusting function.
