摘要
我国目前水泥路面设计规范对行车荷载的考虑主要是80年代以前的情况,调查认为现在公路车辆的超限现象严重,部分轴载已超出规范研究范围,并且路面结构型式也有所变化,因而有必要对原有的轴载换算方法进行外延分析。
The current design specification for cement concrete pavement was made based on the vehicle axle load pattern in the 1980s The axle load survey showed that there were many over loaded vehicles,with some of the axle load over the specified standard;and there are some changes of the pavement structure Therefore it is necessary to reconsider the original axle load conversion method,to make it more appropriate to meet the current conditions
