In this paper, the vibration effect of Longhai Railway on a granary ruins is taken as the research object. Firstly, the vibration response of the granary ruins is obtained by field test. Then, using FLAC3D finite element analysis software to establish an overall calculation model, and the shock absorption effect of vibration isolation barrier is analyzed and predicted. The conclusions are as follows: the horizontal vibration of granary ruins is stronger than the vertical vibration; because of the special structure of the granary ruins, when the vibration propagates to the interface of the cellar wall, it will produce horizontal vibration amplification phenomenon, and the vibration intensity of the granary ruins away from the vibration source will decrease faster; discontinuous concrete isolation piles are used to protect granary ruins. Under the premise of considering more economical, double-row piles with staggered layout have the best vibration isolation effect.
