Analytic Method for Dynamic Analysis of the Track Structure,he field of railway engineering. By establishing the continuous elastic beam model of track structure, analytic method for dynamic analysis of track structure is discussed, and characteristics of ground surface waves and the strong track vibration induced by high-speed trains are analyzed by the ana
