Train velocity has little influence on the dynamic stress and dynamic deformation of subgrade bed, but has obvious influence on vibrating velocity and vibratingacceleration.
列车运行速度对振动速度、振动加速度的影响比对动应力、动变形的影响更显著。

Using theory of vibration wave propagation, the concept of the attenuation coefficient of vibratingacceleration is drawn, and the test results of attenuation coefficient are analyzed.
应用振动波传播理论引出加速度衰减系数的概念,并对加速度衰减系数的试验结果进行了分析。
