In addition, it is also a perplexed engineering problem in designing the under-structural column of ACSR when considering the supporting stiffness to the top of the column. 另外，在设计波纹拱下部结构柱时，如何考虑波纹拱对柱顶支承刚度也是困扰工程界的一个问题。
Both increasing the mass and reducing the support stiffness of the slab can reduce the natural frequency of the FST system to achieve better performance of vibration isolation. 可以通过增加浮置板质量和降低浮置板支承刚度的方法降低浮置板轨道系统的固有频率，以达到较好的隔振性能。
