摘　　要：通过对车速、路面不平度及车辆动载荷之间关系的研究,指出我国等级路面行驶车速限定的不合理性。在超载超限现象严重的情况下,重新审视车辆运行速度的限定,即路面损坏后,应降低车速,以避免道路的恶性损坏。By analyzing the relationship between operating speed, surface evenness and dynamic loads, it finds that the limit of speed about classified highway is irrational. The phenomenon of overload is serious, so the vehicle＇s speed needs to be limited. When the pavement is damaged, the vehicle should reduce the speed in order to avoid the vicious man-made road＇s hazards.

关 键 词：路面不平度 运行车速 车辆动载荷
