摘　　要：为了研究轻交通农村公路水泥混凝土路面的合理面板厚度,以桐乡市为例对农村公路交通量及农村公路水泥混凝土路面的建设现状进行了调查;依据公路水泥混凝土路面设计规范,对农村公路交通量的轴载换算进行了分析,并对不同路面宽度的农村公路水泥混凝土路面在不同的交通量、路面结构情况下的合理面板厚度进行了力学计算。结果表明,桐乡市农村公路交通量组成中,轻型车辆占了较大的比例,标准轴载累计作用次数以及基层顶面当量回弹模量是影响水泥混凝土板厚的主要因素,在轻交通农村公路中,水泥混凝土面板的厚度可以减小到16cm,为轻交通量农村公路水泥混凝土路面技术标准的制订提供了参考依据。In order to study the cement concrete pavement thickness of rural highway with light traffic,the traffic volume and the present situation of the rural highway cement concrete pavement are investigated,taking Tongxiang as example.The axle load conversion of traffic volume is analyzed and the surface plate thickness for highway and pavement width of the rural highway cement concrete pavement in the case of different traffic and different pavement structure is calculated according to the ＂Specifications of Cement Concrete Pavement Design for Highway＂.The results indicate that the proportion of light vehicles in traffic volume composition of Tongxiang is high; times of standard axle load action and equivalent modulus of elasticity for foundation are the main influence on the cement concrete thickness; the cement concrete pavement thickness can reduce to 16cm in light traffic rural highway.The study in this paper provides a reference for the development of the cement concrete pavement technology standards for light traffic of the rural highway.
