尼日利亚与中国沥青路面结构计算对比研究

Comparative Study of Asphalt Pavement Structure Calculation Between Nigerian and Chinese

以尼日利亚某地新建公路项目为背景,结合当地气候特点及交通情况,初拟了沥青路面结构方案,基于BISAR3.0程序,计算了在相应标准轴载下各设计指标的力学响应量,并按照尼日利亚规范及中国规范的要求,分别进行路面结构验算。根据路面结构验算结果,提出了适用于本项目的分别满足尼日利亚和中国规范要求的两个沥青路面结构方案,并对比分析了此两个方案。为海外中方设计人员对尼日利亚当地路面结构计算的认识提供了重要参考。

Taking a newly constructed road project in Nigeria as the background and considering the local climate and traffic conditions,an initial asphalt pavement structure plan was proposed.By using the BISAR3.0 program,the mechanical response quantities of various design indicators under the corresponding standard axle loads were calculated.The pavement structure was then checked according to both Nigerian and Chinese specifications.Based on the results of the pavement structure checks,two asphalt pavement structure plans that respectively meet the requirements of Nigerian and Chinese specifications for this project were proposed,and a comparative analysis of these two plans was conducted.This provides important reference for Chinese designers working on road pavement structure calculations in Nigeria.
