| Abstract: | With the characteristics of military bridges taken into account, the dynamical relationships between the vehicle and the military bridges are studied from the angle of forced vibration of military bridges in the paper, with the factors influencing the impact coefficients of military bridges obtained. The three influencing factors: the span length of bridges, the speed of vehicles and the status of bridge decks, are analyzed, with some suggestions presented. |

| Keywords: | military bridge impact factor span length of a bridge running speed of vehicles deck conditions |
