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
本文首先从典型重载交通道路的交通调查与分析入手,研究了重荷载交通道路的交通量、轴载分布及荷载特征,针对现行设计规范中关于基层顶面当量回弹模量值计算公式存在的不足,利用弹性层状体系理论,按照弯沉等效原则,通过大量的计算分析,回归出了精度较高、适用范围更广的基层顶面当量回弹模量计算公式。
