水泥混凝土路面厚度与合理计算交通量关系的探讨

On Relation between Thickness of Cement Concrete Pavement and Rational Calculation of Traffic Volume

本文结合工程实例 ,分析了新旧水泥混凝土路面设计规范中由于临界荷位的变化导致路面计算厚度的差异。分析表明 ,考虑和不考虑饱和交通的作用 ,可使计算板厚相差0.5cm以上 ;当路上集装箱车辆很少时 ,新旧规范的设计结果相近 ,但当集装箱车辆很多时 ,新规范的设计结果更为合理。

From engineering examples, analysis is made of the difference in calculated pavement thickness caused by variation of critical load positions between the old and new specifications for design of cement concrete pavements. Analysis shows that the difference in thickness may be greater than 0.5m with or without consideration of saturated traffic, and that the design is more rational as per the new specification in case of large numbers of container trucks on the road.
