摘    要:基于重复动三轴试验结果,运用Kenlayer程序计算和1stopt统计分析软件进行非线性回归拟合,建立了一种在车辆重复轴载作用下的柔性路面粒料层永久变形量计算方法,并引入现场修正系数对室内永久变形量预估模型进行修正.结果表明,柔性路面粒料层的永久变形量可通过所提出的回归方程直接计算,并可将其用于中国沥青路面车辙预估.

关 键 词:柔性路面     粒料层    永久变形    回归拟合

Abstract:Based on repeatedly dynamic triaxial test result fitting,using the Kenlayer computational procedure and the 1stopt statistical analysis software,the nonlinear regression and fitting were carried out.One permanent deformation computational method of flexible pavement graded gravel base under the vehicles axle load repeatedly function was established.A scene correction coefficient was introduced to modify the indoor permanent deformation estimate model.The permanent deformation of flexible pavement graded gra...
Keywords:flexible pavement  graded gravel base  permanent deformation  regression fitting
