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，在設計波紋拱下部結構柱時，如何考慮波紋拱對柱頂支承剛度也是困擾工程界的一個問題。
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. 可以通過增加浮置板質量和降低浮置板支承剛度的方法降低浮置板軌道系統的固有頻率，以達到較好的隔振性能。
