摘要: 综合了国内外有关轴重换算的研究资料,分别以路表弯沉等效、基层底部拉应力等效、土基顶面压应变等效及车辙等效为原则,对轴载换算公式中的轴荷指数进行了计算比较,在此基础上提出了合理的轴荷指数.并借助于已建立的轴重分布模型,分析了不同的轴荷指数对路面使用年限的影响.

Abstract: Some national and foreign research results about axle loads conversion are collected in this paper.According to the equivalence principle of surface deflection, tensile stress at the bottom of base, subgrade vertical strain and rut depth, the axle-load exponents of axle loads conversion formula are calculated respectively.On the basis, suitable exponents are suggested.Finally, using the axle-load distribution, the effect of axle-load exponents on pavement lives is analyzed.

Key words: axle loads, axle loads conversion formula, axle-load exponent, equivalence principle, axle-load distribution, pavement life
