实测轴载谱道路当量轴载换算系数的确定

对路面损坏起作用的是轴载，不同的轴载谱可以换算得到不同的当量轴载换算系数。在以往的计算中由于称重仪器的缺乏，采用了近似方法模拟轴载谱；现WIM得到了应用，实际轴载谱的获得已经可能。提出了实测轴载谱条件下道路当量轴载换算系数的确定方法，并结合上海市轴载调查给出了按照道路分类进行的标准轴载作用次数的计算实例。

Determination of Conversion Factor of Equivalent Axle Load Based on Axle Load Spectrum Measured

Axle loads damage the pavements indeeds. Different axle load spectram can be converted into variant load equivalent factors. In the past, the axle load spectrum was simulated by approximate method because of lacking of weight equipments. Now it can be measured by using weigh-in-motion (WIM). A method to calculate conversion factor of equivalent axle load based on axle load spectrum measured is put forward. Then road equivalent single axle load (ESAL) with different classes of Shanghai are calculated.
