阿尔及利亚东西高速公路路线设计的依据为法国规范ICTAAL-1985,本文阐述了该高速公路的几何设计及其与我国的异同,通过对路线平面的圆曲线半径、超高、回旋线以及纵面的纵坡、竖曲线半径取值的对比研究表明:欧洲规范在几何设计上,对于平曲线最小值、最大纵坡的要求基本一致,但不设超高的圆曲线最小半径、回旋线长度、竖曲线最小半径的要求差异较大,总体上欧洲规范的要求要宽松些,给了设计者以更大的操作空间。
Algerian east-west expressway design is based on the French code ICTAAL-1985, this article describes the geometric design of the expressway and its similarities and differences with our country, through the radius of the circular curve of the route plane, ultra-high, swing line and vertical The comparative study on the values of slope and vertical curve radius shows that the requirements of European standard for geometric minimum and maximum longitudinal slope are basically the same. However, the minimum radius of circular curve, the length of gyration curve, the vertical curve The minimum radius of the requirements vary greatly, in general, the requirements of the European norms to be lenient, giving designers greater operating space.
