| Abstract: | The level degree of bridge in different rank has different influence on dynamic response of continuous beam bridge. As been proved, the level degree of bridge is one important factor leading to impaction on bridge. Formulas for impaction coefficient calculation in bridge criterion only fit for good condition of bridge. |

| Keywords: | power chart density bridge level degree action between vehicles and bridge dynamic response impaction coefficient |
