摘　　要： 介绍了沥青路面车辙预测模型,该模型通过落锤式弯沉仪(FWD)弯沉盆反算路面不同层位的模量.采用Kenlayer程序计算各层表面的弯沉和应力,以及各层的永久变形参数,得到了不同荷载作用次数下的预测车辙,并利用足尺加速加载试验来分析该模型和车辙的形成规律.结果表明预测模型能较好地反映加载过程中车辙的形成和车辙的大小. First, a rut prediction model, in which the moduli of different layers were inversely calculated by the FWD （Falling Weight Deflectometer） deflection basin, was introduced. Next, the deflection and stress on each surface of the layer as well as the permanent deformation parameters of each layer were calculated using the Kenlayer program. Then, the ruts with different loading repetition numbers were predicted. Finally, a full-scale accelerated loading test was carried out to analyze the rut prediction model and the rut formation law. The results indicate that the prediction model accords well with the formation and size of the practical rut.
