| Abstract: | A dynamic infinite element method was adopted to calculate and analyze the dynamic response of flexible pavement under Falling Weight Deflector(FWD) load.Moreover,the effect on stress,flexure and relative parameter between each layer was discussed and investigated.The result of this paper can be as referemce for working condition of flexible pavement under an actual dynamic load. |

| Keywords: | dynamic finite element Falling Weight Deflector flexure basin |
