摘要：
Taking the subgrade section of Gu'an east station of Jingxiong intercity railway as the test section, this paper studied the evolution characteristics of vibration wave under different compaction parameters from four aspects of time domain, frequency domain, time-frequency domain and energy domain. The results show that in the process of subgrade compaction, with the increase of the running speed of the roller, the peak acceleration of the subgrade filling decreases, while the peak acceleration of the vibrating wheel increases. The attenuation rate of the acceleration of both gradually increases. With the increase of compaction times, the attenuation rate of acceleration peak value of vibration wave propagating along the horizontal direction in the filling decreases gradually. In the process of the vibration wave propagation from the vibratory wheel to the filling material, the amplitude of the fundamental wave, the first harmonic wave to the fifth harmonic wave is exponentially distributed with strict exponential function correlation. Upon the Hilbert Huang Transformation of the vibration signal, with the increase of the compaction times, the peak energy of the vibration wave in the vibratory wheel and the filling material increases gradually. With the increase of the traveling speed of the vibratory roller, the energy peak of the vibration in the vibratory wheel and the filling material decreases gradually. © 2020, Department of Journal of the China Railway Society.
