随着我国交通建设事业的不断发展,高等级公路的建设数量不断增多,促进了我国现代公路交通网络的构建。与普通等级的公路工程相比,在高等级公路的设计中,要综合考虑线形、景观、路基高度、路基及路面排水、边坡等项目,以保证公路的行车安全、通行质量与使用年限。本文结合笔者多年高等级公路设计经验,简要分析了设计工作中应注意的一些问题,仅供同行参考。
With the continuous development of China’s traffic construction, the number of high-grade highways has been increasing, which has promoted the construction of modern highway transportation network in our country. Compared with common grade highway projects, in the design of high-grade highways, the projects such as line shape, landscape, subgrade height, subgrade and pavement drainage and slope should be comprehensively considered in order to ensure traffic safety, traffic quality and service life of the highway. This article combines author’s years of experience in high-grade highway design, briefly analyzes some problems that should be paid attention to in design work, and is only for reference of peers.
