摘要
通过轴重调查,获得重载车对路面的荷载状况。针对一般和两种特殊状况,通过理论计算获得重载车弯沉与轴重关系,由此推得超重轴载下的沥青路面理论轴载换算公式,再综合天津市实测弯沉分析结果。
Based on the result of axle load survey, the loading condition of overloaded pavement is discussed.Then the theoretic relationship between axle load and deflection is calculated,respectively to three different conditions (one ordinary, two special).At last the axle conversion equation of overloaded axle on asphalt pavement,which is validated to some extent by the result of Tianjin deflection survey,is recommended.
