摘要
给出了具有较高精度的两层路面结构模量反算回归式,在此基础上,讨论了弯沉测量误差和面层厚度偏差的传递效应。最后,定量分析了FWD系统的随机误差和面层厚度误差对面层和地基模量反算结果的影响。
The regression equations are well developed to back-calculated the moduli of 2-layer pavement. The transferring effects of errors of sensor deflection and layer thickness are then discussed based on regression equations. Last, it is quantitatively analyzed that the random errors of FWD system and layer thickness arrors affect the back-calculated results of muduli of layers and road bed.
