摘要
通过多轴车轴载谱调查以及不同荷载作用下路面结构的受力分析,采用国外的路面疲劳寿命计算公式以及沥青面层永久变形计算公式,建立起不同轴重的多轴荷载与标准荷载之间的换算关系。计算结果表明按照国内换算方法得出的交通量能满足路面的疲劳开裂的要求,但不能确保路面的抗车辙性能。
Through investigation of multi-axle load table and mechanical analysis of road surface structure under loading,by the way of foreign formulas of fatigue life and asphalt surface permanent deformation,this paper established conversion relations between multi-axle load in different loads and standard load.Calculation results show that the traffic calculated in accordance with domestic conversion method can meet the requirements of fatigue cracking,but can not ensure the road-track performance.
