摘要
德国是最早修建高速公路的国家,同时也是世界运行效率最高最安全的高速公路之一,研究德国高速公路设计具有重要的参考意义。介绍了德国高速公路设计等级体系和其基本特征,分析了我国高速公路设计和德国高速公路平面、纵断面、横断面的几何设计要点。利用了德国高速公路设计指标体系分析了京港澳高速某段的线形要素。研究表明德国高速公路横断面设计与我国基本一致,平面和纵断面线形指标相较我国规范总体上更为宽松,但德国规范对平面直线长度和最小纵坡要求更高。
Germany is the first country to build highways,and also one of countries that has the most efficient and saf est highways in the world.Therefore,it is of great importance to learn from German highway design.This paper introduc es design hierarchy and basic characteristics of German expressway,and then analyzes the geometric design points of plane,longitudinal section and cross section of expressways both in China and Germany.The alignment of a section of Beijing-Hongkong-Macao expressway are also analyzed by using German expressway design index system.The research shows that the cross-section design of German expressways is basically the same as that in China and the alignment in dex of plane and longitudinal section are generally more relaxed than those of our country,but it requires a higher straight length and minimum longitudinal slope according to German standard.
