In this paper , the traffic surveys and analysis of typical heavy - load road were performed firstly ; also the characteristics of traffic , load and distribution of axle load were studied . the deficiencies in the calculation method of surface equivalent modulus of foundation in present specification of cement concrete pavements design for highway were analyzed . based on the elastic multi - layer theory and principles of displacement equivalence , and a great amount of computing data , a calculation method was established 本文首先從典型重載交通道路的交通調查與分析入手,研究了重荷載交通道路的交通量、軸載分布及荷載特征,針對現(xiàn)行設計規(guī)范中關于基層頂面當量回彈模量值計算公式存在的不足,利用彈性層狀體系理論,按照彎沉等效原則,通過大量的計算分析,回歸出了精度較高、適用范圍更廣的基層頂面當量回彈模量計算公式。
