山区通村公路水泥混凝土路面轴载换算方法的研究

通过对承德地区山区通村公路的轴载谱进行分析研究,阐述了现行水泥混凝土路面轴载换算方法,并提出了其作为通村公路轴载换算标准的局限性。运用ANSYS有限元软件分析计算,重新回归了荷载应力公式中的相关系数,推导了通村公路水泥混凝土路面的荷载应力公式和轴载换算公式,可为山区通村公路水泥混凝土路面设计提供参考。

Research on Axle Load Conversion Method of Cement Concrete Pavement for Country Roads in Mountainous Area

Through the analysis of the axle load spectrum of country roads in Chengde mountainous area, the existing axle load conversion method of cement concrete pavement and the limitation of the method used in country roads are described in this paper. With the help of ANSYS finite element software for analytical calculation, the correlation coefficient of stress equation was regressed again and the load stress equation and axle load conversion equation for cement concrete pavement of country roads were derived. Thereby this study provided references for the design of cement concrete pavement of country roads in mountainous area.
