| Abstract: | Taking Datong city-rounding highway engineering practice as the background,the paper studies the dynamic response of the subgrade under vertical and horizontal seismic,and analyzes the vibration speed,acceleration speed and deformation time history,and concludes that the eternal subgrade section deformation owing to earthquake is basically symmetric,and the deformation of middle and two lateral sides are rather big. |

| Keywords: | seismic load subgrade dynamic response deformation property stability |
