The high-speed railway of China mainly adopt the structure of ballastless track. When trains run in high-speed, the vibration strength and anti-impact capacity born on the track are directly linked to structural elasticity of the track. The vibration strength has a direct influence on trains' stationarity and security, and will make a noise to ambient environment. Based on track bed of ballastless track, sensitivity analysis on structural elasticity shows that improving the track bed situation, raising the elasticity of resilient pad under the rail and focusing on the uniformity of longitudinal elasticity in rail are very crucial to track elasticity.
