| 摘 要： | 就高速公路不同车道上不同车型的轮迹分布特点进行了研究,确定了高速公路双向四车道、六车道和八车道在考虑不同情况下的车道系数和标准轴载轮迹横向分布系数推荐值,给出了按照一定的规则将从观测站或收费站得到的双向或单向年平均日交通量和交通组成换算为设计所需的等效标准轴次的两种不同方法,为更科学合理地确定高速公路的等效标准轴次提供了可能.

| Abstract: | The distributing characteristics of different types of vehicles on different lanes of freeway are researched.The lane coefficients of different lanes for considering different status and the standard load wheelpath lateral distribution coefficients are given for double-direction four lanes,six lanes and eight lanes of freeways in the paper.And,the authors developed two different methods for transforming double or single direction annual average daily traffic(AADT) and traffic composing from observation station or charge station into equivalent standard load times that structural design needs,according to the definite rules,which provides the possibility for more reasonably ascertain equivalent standard load times of freeway. |
