First, the axle-load distribution model of heavy vehicles are constructed on the basis of statistical data.

本文首先根据调查统计数据，建立了河北省干线公路上载货车辆轴重分布模型；

The requirements on steel types and features of wheels with increase of axle load of heavy haul vehicles are discussed.

介绍了大秦线车轮的服役表现，探讨了重载运输条件下车辆轴重增加对车轮钢种特性的要求。

And the results from rutting predict-equation with the the equation of axle load conversion under heavy-load fit the testing results well.

实验证明，利用该这个公式，再通过车辙预估方程计算的车辙与直道实测车辙数据拟合情况较好。
