多年来，地震激励过程中与地面的隔离一直是研究人员面临的难题之一。从目前的方法来看，一般的原则是通过在结构和基础之间插入一层低水平刚度的层来将建筑物或结构与地震地面运动的水平分量解耦。结构基底的和谐运动将导致基频的显著降低，远低于其固定基频，也远低于地面运动的主要频率。
Isolation from the ground during a seismic excitation has been one of the challenging subjects for researchers for many years. From the review of current approach to date, the general principles are for buildings or structures to be decoupled from the horizontal components of the earthquake ground motion by interposing a layer with low horizontal stiffness between the structure and the foundation. The harmonious movement of the structural basement will cause a significant reduction of fundamental frequency that is much lower than its fixed-base frequency and also much lower than the predominant frequencies of the ground motion.
