Guangzhou-Shenzhen-Hong Kong High Speed Railway Shiziyang Tunnel is the longest and highest operation speed of the first high-speed railway double line shield tunnel. To ensure the safe operation and further reduce the influence of running high speed railway train on tunnel stratum and structure, vibration damping ballastless track is adopted in Shiziyang Tunnel. The paper has studied the Shiziyang Tunnel structure design, determined the reasonable damping cushion stiffness. In Shiziyang Tunnel commissioning period, ballastless track vibration test is carried out to evaluate the vibration damping effect and the safety and comfort when high-speed train is passing through, to verify the design parameters of vibration damping ballastless track, to provide technical basis for further optimization of high speed railway ballastless track vibration damping design.
