In an earthquake high-intensity area, the vertical earthquake motion component is large and even exceeds the horizontal earthquake motion component, the damage effect of the vertical earthquake motion component on the structure cannot be ignored, and the damage effect is particularly obvious in the vicinity of the epicenter and earthquake-initiating fault. Meanwhile, with the development of urban rail transit, the influence of vibration caused by the subway in the operation process on the structure is increasingly prominent, and the comfort level of people living is seriously influenced.

When the structure suffers from an earthquake with a super-design standard, the structure can swing to enable the support to enter a tension state, the thick-layer rubber laminated support can be damaged by tension, the steel spring support can be lifted away by stress to cause failure, and the safety of the upper structure is seriously affected.
