Predict the Influence of Environmental Vibration from High-Speed Railway on Over-Track Buildings

The vibration caused by railways is an environmental constraint in the development of over-track buildings. To study influence from high-speed railway on buildings, a finite element model including track, soil, and buildings was set up. Based vertical acceleration sampled rail, equivalent line load acting rails vertically obtained simplified model. On basis verifying simulation measurement results, induced studied quantitatively. Through introducing correction terms relating to thickness height platform, story number, structure building, existing released industry China improved. Compared with only being suitable for predicting first floor, improved can predict different floors.
