行车动荷载作用下路面平整度的预估

Calculation of pavement evenness under dynamic load of moving vehicle

以正弦曲线模拟路面表面,建立了车辆振动模型,给出了车辆在不平整沥青路面上行驶时产生动荷载的计算方法及在动荷载作用下路面平整度的预估方法,并结合某高速公路路面平整度进行了检测。结果表明,给出的计算和预估方法可靠,为分析路面平整度的发展变化规律提供了一定的理论基础,为评价沥青路面的使用性能及路面的维修养护提供了技术支持。

The pavement surface was imitated by using sine curve, the vehicle vibration model was established, the calculation method of dynamic loads of driving vehicle on unevenness asphalt pavement and the estimating method of pavement evenness under dynamic load ware given. The calculated results were proved to be reliable throuch comparing with actual measured results. This method provides a theory basis for analyzing developing tendency of pavement evenness, and gives a technical supporting for the appreciation of performance and maintenance of asphalt pavement.
