针对目前水泥混凝土路面错台预估存在的不足,通过现场调查发现无论设置传力杆与否,错台量与脱空高度均存在良好的相关关系,并在试验室内修筑基层脱空的水泥路面结构,分析行车荷载与冲刷量的关系,试验表明:二灰稳定碎石基层和水泥稳定碎石基层的冲刷量均随着轴重的增加呈指数增大.最后建立两种不同基层类型的考虑冲刷脱空的水泥混凝土路面接缝错台预估模型,并通过柳南路对不设传力杆的二灰稳定碎石基层错台模型进行验证,结果表明模型具有很好的应用性.
According to the shortcomings of the current prediction of the dislocation of cement concrete pavement, we found that there is a good correlation between the dislocation height and the height of dislocation, no matter whether the dowel bar is installed or not, and the cement concrete pavement Structure and the relationship between driving load and erosion amount were studied.The results show that the erosion amount of the base course of lime-flyash stabilized macadam and cement stabilized macadam increases exponentially with the increase of axle load.Finally, two different types of grassroots are established The prediction model of seam stagnation of cement concrete pavement with scouring void was validated and the model of lime-lime stabilized gravel staged fault with no dowel bar was validated by Liunan Road. The results show that the model has good applicability.
