In traditional techniques, trenching is generally used to reduce the impact of high-speed trains on surrounding buildings. To explore the effectiveness of this method, we use a combination of numerical simulation and on-site experiment to verify the vibration isolation effect of isolation ditches. Based on large-scale finite element software, we compare numerical models with on-site experimental results, and analyze the dispersion characteristics of Rayleigh wave elliptical polarization as high-speed trains pass through viaduct. The results show that when high-speed trains pass through viaduct, a stable surface wave field is formed, which is like the excitation of a single point seismic source. When an isolation ditch is installed on the line, the soil vibration behind isolation ditch shows a certain degree of attenuation, and the isolation effect is obvious.
