Abstract: In the condition when different track structures are adopted by the test line of metro vehicle base with cover property, the vibration influence on adjacent buildings caused by train passing is simulated by finite element analysis. The results show that compared to the ordinary ballast bed, the proposed floating slab ballast bed can significantly reduce the vibration impact of the test line on adjacent buildings. At the initial stage of metro vehicle base cover property construction, it is necessary to analyze the vibration and noise impact of train operation on the project to be developed, corresponding vibration reduction measures should be taken in the track structure to reduce the impact.
