柔性路面力学敏感性正交分析设计

Orthogonal Analysis on Mechanical Sensitivity of Flexible Pavement

采用正交分析法分析了不同柔性路面设计指标随路面结构层厚度变化的力学敏感性,并得到了在等经济性变化及等厚度变化两种不同条件下路面结构各层厚度变化对设计指标的影响程度;并以此为基础,给出了仅考虑经济性或仅考虑厚度条件下的路面结构对比实例。

The orthogonal analysis method is used to analyze the mechanical sensitivities of the different flexible pavement design indices with the change of the thickness of pavement layer, and to obtain the influence degree of the thickness change of pavement structure layers on the design indexes under the two different conditions of equal economy and equal thickness. Based on this reason, the article introduces the contrast cases of pavement structures under the condition of only considering economy and thickness.
