车辆通过连续配筋混凝土路面冲断区域时影响行车舒适性的因素较多，有必要对其进行深入研究并找出主要影响因素。文章首先建立冲断区域人-车-路耦合振动模型，通过求解振动方程获得乘客加速度随时间的变化；然后考虑行车舒适性，以最大瞬态振动值作为行驶舒适性评价指标；最后分析冲断区域数量、行车速度、冲断区域台阶高度、路面纵坡坡度、选取路面板大小和上下坡等因素对乘客行车舒适性的影响。研究发现：当车辆经过冲断区域时，冲断区域数量、行车速度、冲断区域台阶高度和路面纵坡坡度对行车舒适性影响较大。建议当车辆通过冲断区域时，驾驶员可降低车速以提高行车舒适性；当冲断区域台阶高度较大以致严重影响行车舒适性时，应对路面进行维修。

There are many factors influencing the riding comfort when the vehicle passes the punch-out area of the continuously reinforced concrete pavement ,so it is necessary to further study these factors and find the main .Firstly ,the human-vehicle-road coupled vibration model in punch-out area is estab-lished and the vibration equation is solved to obtain the passengers acceleration over time .Secondly , the driving comfort is taken into consideration and the maximum transient vibration value is used as the riding comfort indicator .Finally ,the influence of the number of punch-out area ,driving speed , bench height ,degree of longitudinal slope ,pavement plate size ,upslope and dow nslope on the riding comfort is analyzed .The results indicate that the number of punch-out area ,driving speed ,bench height and degree of longitudinal slope have a great effect on the passenger ’s riding comfort w hen the vehicle passes the punch-out area .It is suggested that the drivers can lower the driving speed to im-prove the riding comfort w hen the vehicle passes the punch-out area and the road must be maintained w hen the bench height is high enough to affect the riding comfort seriously .
