双轴车辆的轴数系数研究

A dissertation on research on axle-number coefficient of double-axles vehicle

利用Kenlayer弹性层状体系计算程序,分析在典型的半刚性基层路面下,各结构层参数对以不同设计指标进行轴载换算时的轴数系数的影响,确定对轴数影响比较显著的指标;通过拟定不同的结构层参数,进行回归分析,得出不同设计指标的轴数系数修正公式。

By use of Kenlayer programme based on layer - elastic theory, analysis the influency of structure - layer parameters to axle-number coefficient while carrying on axle -load exchange based on typical semi -rigid base asphalt pavement; figure out the struc-ture -layer parameters that influence the axle -number coefficient significantly; by the result of regressing analysis by using differentstructure -layer parameters, the axle -number coefficient formular using for different design indicators is recommened.
