由于地震动在水平向和垂直向的差异，决定了隔震装置需要按各向异性性质设计。以新西兰的铅芯橡胶支座和专用于浮放设备的隔震支座为例讨论了确定隔震装置的设计参数的要点、隔震装置结构形式选择等问题。
Due to the difference of horizontal and vertical ground motions, it is decided that the isolation device needs to be designed according to the anisotropic nature. Taking the lead rubber bearing in New Zealand and the isolation bearing dedicated to the floatation equipment as an example, the key points to determine the design parameters of the isolation device and the selection of the structure form of the isolation device are discussed.
