近年来,随着我国国民经济的快速发展,交通量迅速提升,很多原有县乡公路已经不能适应日益增长的交通需要,急需改建。由于改建公路与新建公路的建设条件有很大不同,路线设计受到的制约因素较多,因此,改建公路的线形设计一直是设计人员比较关注的问题,本文简要探讨了县乡公路改建项目线形设计需要注意的问题。

In recent years, with the rapid development of our national economy, the traffic volume has rapidly increased. Many of the existing county and township roads have been unable to meet the growing traffic needs and are in urgent need of alteration. Because of the difference of construction conditions between the rebuilding of a highway and the construction of a new highway, the route design is subject to many constraints. Therefore, the linear design of a rebuilt highway has always been a major concern for designers. This paper briefly discusses the linear design of the rebuilding project Need to pay attention to the problem.
