道路在正常通行过程中对路面承载能力进行检测,关键的问题就是如何确定车辆正常通行过程中对路面的动力作用~([1])。车辆在正常行驶过程中对路面产生的动荷载与车辆行驶速度、路面不平度以及车辆本身的振动特性等因素有关~([2-3]),是一个极其复杂的问题。确定了车辆动态荷载,才能通过实时监测的路面动位移或动应变信号进行分析,从而实现对路面承载力的评价。
Roads in the normal passage of the pavement carrying capacity testing, the key issue is how to determine the normal passage of vehicles on the road during the dynamic effect ~ ([1]). The dynamic load on the pavement during the normal driving process is related to the vehicle running speed, road roughness and the vibration characteristics of the vehicle itself ([2-3]), which is an extremely complicated issue. Determine the dynamic load of the vehicle, in order to real-time monitoring of the road surface dynamic displacement or dynamic strain signal analysis, in order to achieve the evaluation of the road surface bearing capacity.
